Hi agamy, I'm having the same problem and rebooting the phone doesn't help either.
Were you able to find a solution?
Do you guys still have this problem? Figured out a fix? I don't have one but this guy I know does. Thanks!
Yeah, return it if the speaker keeps shutting off. Mine was doing the same thing and I just called the tmobile and they're sending me another one (actually my second replacement as the other one had serious software glitches).
Ok I will let him know. Thanks!
I've had the same issue with mine for about 2 months. The speaker was working fine then every now and again when I would type it would get very loud then cut off for me, Wouldn't not turn on for anything. last night it started to work but only at 1 on volume. I turned it up to half way and was excited that it worked again, kept locking and unlocking getting messages etc. Then I went to go type and boom! speaker went out again, now I'm left speakerless yet again. I don't ant to get a replacement yet because I have a skin case on it and I would have to pay for another when I get the new one. I've never ever had any issues with speakers on any other phone I've had so I'm quite disappointed.
i now am experiencing the same problem. while playing a game (assasins creed) the speaker just died down on me. at first i though it was just the game. tried other games and zune,none of them have sound. done with reboot and restart,unfortunately still no volume. im stuck with an expensive phone wihout volume,another unfortunate thing is,i cant even have it replaced since i bought it in ebay.
i hope somebody will have a fix to resolve this issue
cheerio
I had the same problem and after a week or so everything is back to normal.
just had mine fixed.sound is back audio is as great as when i received the phone.im just worried if the same problem would occur. it took two days for htc service center here in the philippines to fix it.
:-( I have the same issue, I was playing music and the speakers dead!!! I don't even touch the phone......the speakers only stop working without any reason. Somebody can fixed that problem? Because I'm in Ecuador and here we don't have an HTC repair center.
I have similar problem with speaker, volume is stable but not loud enough. I am not sure if it is a software problem or hardware one.
Regards
try reset, or flash rom with higher version.
Maybe the sys bug.
I have the same problem! Hard-reset and flashing a newest rom doesn't help! I think this is hardware problem(
Somebody knows, where it is possible to find replacement speaker for it. And where I can find service-manual? Thanks!
My speaker just went dead as well. Highly annoying because the phone's useless as an alarm now. Traveling abroad at the moment, so might not even be able to get it fixed...
Hi guys,
I had the same speaker problem on my brand new brand new HD7 a while back. Back then i used to use the alarm and snooze a lot. After a couple weeks of alarm going off and snooze, the speaker gone mute. This is a wide spread problem HTC Window7 phones, especially this HD7 model. I tried everything from sound enhancer app to flashing custom ROM, but could not find any solution. So i let it sit for like 4 months until that one night i decided to mess around with it again. It was 2 in the morning so it was really quiet. That was how i found out that the speaker was still working but only output really little sound or static even if i had the volume at max.
So just a wild guess, i googled the part for the speaker and how to dissemble the damn thing. It's pretty easy and i happened to have a broken g1 which had the same loud speaker with the HD7. So i switch them out and voila, i got the sound back.
I was so excited so i tried everything that output sound on the phone. Everything worked out fine for like ... 2 days! Speaker went out again! During that 2 day, i was doing a lot of music, video, games . But i noticed things get really glitchy during keyboard clicking and and snoozing off the alarm.
So i'm pretty sure the G1 speaker is dead again. So i went on ebay and bought a brand new OEM speaker for the HD7 for 4 bucks (G1, G2, HD2, and some other models use the same one. Check the picture). 3 days later and another trip to the inside of the phone, It sounded loud and clear again. This time i completely avoid the alarm and keyboard clicks. I have got sound for almost 2 month now.
So if you don't have sound. Hold the phone to your ear and play something. If you hear hiccups, little sound, or static coming out then it's not a software problem. Replace the speaker and avoid using the alarm and keyboard clicks.
Hope this solve your problem.
this happened to mine for a while until eventually it gave up and had to be returned to be fixed... luckily it was 11 months old and still in the initial 12 month warranty... speaker replace and now all is fine.
If yours is going and it's still in a warranty period, I'd return it to where you got it from.
"The Fonz" Method
Not a real great fix, but I fixed my wife's phone by hitting the top of the backside of the phone pretty hard with the palm of my hand (or set it down hard on a table). It was working for a few weeks and we were sitting at the dinner table one night and I set it down, and it worked for a second. Then I thought, "Maybe if I hit it harder it will come back on." And it worked! Probably a loose wire or something.
Hi guys,
i think there's a problem in my i9000;
whenever i make a call, i can hear low static interference in the background.
i searched both on xda and elsewhere, and although some other people complained of this problem, no one was able to determine the cause or provide a solution.
i tried different roms, froyo and gingerbread samsung roms, in addition to cm7, with different kernels and modems, heck i even changed my csc(just for sake of changing everything to make sure.. all for nothing. the problem persists.
Does anyone know what might cause such problem and how it may be solved?
i have exactly the same problem. Like you; i tried every combination which i can. I think main cause of the problem is hardware related. But my opinion is ,it can be fixed with device drivers. I looked at service manual. In the speaker part of the service manual,you can see there are two inductors and one capacitor before the speaker module. You can see the full circuit in Service Manual Page 42.
h**p://img191.imageshack.us/img191/2383/speakerj.jpg
I think these inductors(L209,L210) are interferencing with the GSM frequencies and making that static sounds on the background.
We need someone who is an expert on linux and device drivers. Maybe he can show us to find a way to break this circuit(temporarily turn off B1 and A2 pins) in a call so it will not make that sounds.
In the other hand we may have defect phones. May be the only way is to change some parts.
sorry for my bad english.
I think there's something wrong with the speaker itself.
I'm taking the phone to samsung's maintenance to see what they have to say about it.
I'll report back once i get to the bottom of this..
Same here, but it's not constant, just happens enough to be noticable, bloody annoying, and only started (or I only noticed it) a couple of days after JVP. Will be interesting to see what you find out...
One possibility, do you have your phone in a magnetic flip case? Worth checking

No magnetic flip case, just a hybrid (plastic back+sillicon frame) cover.
I even took it off for a while to see if it was causing the problem, but no.
I went to samsung service center and they said it will cost about 200$ because the ear piece comes with the touchscreen..
Meaning i would have to pay for a new touchscreen even though i only need the ear piece.. How about that for service.
I checked ebay and found the whole ear piece+speakerphone+headphone jack in one bundle for 15$
so guess what my next step will be??
Buy and install the ebay part, sell my i9000(never liked tw anyway+cm seems a long way from home).. Had enough samsung for one lifetime
are you sure about the sound is coming from the earpiece ? i am asking because few weeks ago i was also assuming that the interference sound is coming from the earpiece . But i realized that it is coming from the rear speaker. Can you test it ?. In a call ,turn back the phone and put speaker hole to your ear. The interference sound is so loud that you can hear it from the earpiece hole.

This is the question which i am also looking for answers
Everyday i am searching for answers. Only a very few people experiencing this problem.
I think this problem is coming from the inductors in the speaker circuit part. You can look my first post .

i have this problem too, i live in Romania, i tough my phone was broken, but a friend's phone also does that.
i notice it when making call while 3G data was running in the background. If 3g is off = no noise.
Also i have noticed, the way you hold the phone affects it. try holding it with 3 fingers to your head the covering the mic hole with the other. you should hear some interference right there. so it's probably: speaker+ extra sensitive mic + some antenna things
Also my friend had the phone for some months now and never noticed it i searched the web and we're not alone, i found this discussion on a couple of other forums, still nothing to do, or nobody reported back after they whet to the warranty service. i would go, but i don't have any warranty on mine.
I'm also from Romania and I noticed this annoying issue today. All my other friend with Galaxy S also have this problem, so I guess it's a normal thing.
The only solution, I guess, is to use 3G networks, at the risk of draining a bit more battery.
so bottom line is that on mine, i hear noise/buzzing/interference when i use 3g networks both on the speaker on the back and the earpiece (it's louder if i use 3g data while i'm making a call) - the issues goes away completely in gms(2 g) mode
and it depend on how i'm holding it - it's louder if i grip the phone in my hand (probably the wireless signal is lower and the phone increases the power needed to communicate to the network thus experiencing buzzing sound from the speakers like radios did back with the first cell phones before receiving a call)
so i guess i'm not the only one, right?
This issue is normal I think. No big deal. If the noise however gets so loud that it interferes with your call, get it changed. But the new ones you get might have the noises too. So what is important here is to keep the noise to the minimum.
With / Without the noise is totally an unknown cause now. At least have it settled to the least noisy.
*This is happening to everyone who is getting the phone since November 2010
I confirm this issue with more models.
Hi guys!
Bought myself my GT-S5570 (Galaxy Mini) a couple of months ago. This is my first Android experience. At first I was pleased, but then I noticed this static noise whilst in call. It's like, suddenly I can have ill-isch, distorted, "noise spikes" sort of things. Left my phone in for service under warranty. When I had it back, it was still messy. Bought myself a GT-5660 (Galaxy Gio) a week ago, thinking that this one would clear the issue. It's still there, though. I'm wondering if this is something that affects the whole Galaxy series, even the tougher models like S/S2.
Related threads, by me:
android.net/forum/samsung-galaxy-mini/60951-sudden-volume-spike-during-call.html
androidforums.com/samsung-galaxy-s/307523-samsung-galaxy-s-gt-i9000-static-ear.html
yesterday my cousin bought i9000 too. First of all i looked for the noise. It is interesting that that phone is nearly noise free. If i gave 10 point noise to my i9000 than that phone will be 2 points. You can hardly hear the noise. After that i get her SIM card and test my phone with that sim card.Noise is still there.I make that phone software same with my phone. That phone still has no noise.
I think the problem is in phone parts. Maybe a defected series of speakers used in our phones. I will buy a new speaker module on internet. I hope that fix my problem.
For me it depends more of the network I use than the phone. It happens sometime with an iPhone.
as i stated in my previous post in this thread, in my case i was sure it was the loud-speaker, i say "was" because i sold the phone, and thats the reason why i didn't come back to this thread since..
it seems there was something wrong with the loudspeaker(on the back of the phone), and it was, at least to me, one of those things where a person might not really notice unless you're looking for it.. my bad luck had caused me to flash a certain modem and the reception was bad, so once i reverted to the previous modem i was checking for the sound clarity and that was when i first noticed the static during calls..
then i realized it was coming from the speaker, as one good man in this thread suggested. i couldn't handle it though, i could hear it every time i make a call..
it didn't make a difference whether i was on 3g or gsm or both, it was always there, unless i went into airplane mode..
so i ended up selling the phone, and bought another, but before i had bought it i put my sim inside and made sure there was no static, and there isn't, whatsoever.. thank god.
i'm sorry i couldn't find any other solution to the problem, samsung service here had said they would replace the speaker, as the part comes on its own, unlike the case for the phone speaker, which, according to samsung, is bundled with the screen, and if i had wanted to change it i would have had to pay something like 200$ to fix...
those who have this problem, check if its the loudspeaker on the back of the phone is the actual culprit, and if it is, try to find a way to replace it or something, that is if it bothers you this much. or you can just sell the phone, there's a 99% chance those who buy it won't notice anything, because they're not looking for it..
good luck guys..
Hi Forum,
I orginally posted this topic on the man Q and A board but it was buried quickly with no response. Perhaps this is a better venue to ask.
My phone is roughly a year old, and today I ran into a weird and potentially phone killing problem
I received a few phone calls from my girlfriend today, the ringer rang loud and clear, but I heard no sound from my ear piece. After a few "Hello?"s, I hung up thinking it was a bad connection. Upon seeing my girlfriend afterwards, she said she heard me on my end. So I got her to call me again and I tried to use speaker phone, and I could hear her fine.
Doing some research on google, I only ran across one other person who had this problem, and upon seeing this, I tested my music player, (as theirs didn't work), and mine doesn't work either
This other person said the problem resolved itself a day later.
In short, my ear piece has no sound during a phone call and my media sound doesn't work (though it works w/ headphones.) My notification sounds and speaker phone DO work, as well as my alarms
Do the notification and speaker phone speakers come from a different place than media and ear piece speakers?
Do I have a software issue? I tried the "push the speaker down" solution but to no avail
Should I wait like the other person?
Any suggestions?
Thanks forum!

I had nearly the same issue, except mine got to the point where the speaker phone didn't work either. Music played fine, phone calls stopped working. I went through a lengthy process of accidently deleting everything I had on my phone, which lead me to buy a USB Jig, install the stock ROM and it worked perfectly. I would suggest trying this before you try and physical fixes on your phone.
Thanks for the suggestion SGT_Watkins
I am an absolute noob when it comes to this stuff. So it took me a while to even figure out what you were saying
BUT, after a whole night of reading and flashing it WAS FIXED!!!
I am quite tempted to phone Samsung and give them a piece of my mind after they told me some hardware was defective even though they clearly weren't listening to what the problem was
Thank you again!
How did you solve this?
I have the EXACT same problem on my Galaxy Nexus. I've wiped it, tried different ROMs, kernels... Nothing solves it! It's like there's a persistent software problem that survives flashing and even battery pulls.
My phone had this same issue not long ago. It was after I had used some headphones for about an hour. I work in a paper converting factory, so I assume some dust was packed in the headphone jack and made the phone think something was plugged into it. I turned my phone upside down and used a paper clip to scrape it all out (compressed air may have been safer). After a few tries, all sounds were working properly again.
Sent from my SGH-I897 using XDA
Here's the story: My Nexus 6 top speaker is making static/buzzing/white noise. I've gone through THREE different Nexus 6 devices already and I am extremely annoyed about this. I am pretty sure the first device didn't have this issue or else I would have noticed it, but it did have an extreme battery drain issue. The second one definitely had this same problem, which was why I got this third one.
After some rigorous testing, I noticed that the static occurs when you are locking the phone with the volume on, it gets louder when your phone is below ~20-25% battery and basically whenever the top speaker turns on (INCLUDING when you are actually talking on the phone, which bugs me the most). BUT, once you plug in the charger, the static goes away completely and will never occur until you unplug.
The fact that the first phone didn't do this bothers the crap out of me because now, I'm paying for a an extremely expensive phone with a hardware defect (At least my previous iPhones never had any hardware problems...).
Is anyone else experiencing this? I have seen a few threads on XDA but nobody really replied; also, there are Reddit posts about this and something has a Google Doc Group opened, but nobody's really addressing the problem. If this is a software issue, I'd be more than happy to sit and wait for an update, but if it's a hardware issue, then I want a new phone..
I get static when my phone starts to ring or get a notification sometimes. It sounds like its lagging, loud, and heavy crackling. Im pretty sure this isn't hardware related and will be fixed with a software update
I've got it too so I don't think it's your phone.
Seems more like a lag/software issue. I too was thinking it would be addressed in a software update so I wasn't too concerned. Music sounds OK and so do my calls so um yeah.

I hear it when I'm on calls as well, which is the most annoying part. I think I'm going to swap it in one more time to be sure... It doesn't cost me any money, I'll post an update when I get the new one. In the meantime, is anyone else getting this?!
Yeah I don't get it on calls that I've noticed. Mostly system sounds when I get notifications and various apps become active like I'm getting some lag maybe? I've noticed though that this phone is so fast its nothing for me to have 20 or 30 things open in the background and not realize it so I'm not sure if that was part of it I'll have to pay attention for a few days I guess

Same issue on my side. I don't think a lot of people have the phone yet so maybe that's why you aren't getting a lot of replies. I am getting a ton of white noise especially while on a call. Its so loud that its really distracting and hurts my ears. I returned my first one because it was defective and wouldn't make or receive calls and nobody could figure it out. Now I have this one with tons of white noise and static. Very disappointed with nexus. I was expecting quite a jump from the nexus 5 and with having a defective phone from the get go with the 6... Im about to divorce the nexus brand altogether

I'm officially on my 4th Nexus 6 and to my dismay, it is still there. Going to pray that it's a software bug and hope it goes away since my 14 day grace is up. Any other insights would be great..!
I get it a little on some incomming notifications , i'm pretty sure its not the actual hardware though , playing music or youtube videos doesn't have any distortion or noise.

Thanks for the update! I don't believe our issue is the same as the one you documented on your video. My speakers work fine and don't crackle that way during normal use and it is only the top one when you put your ear close to it or if you are in a quiet room (which I am, majority of the time when I'm at home).

Yep, I tested it out of the box stock everything right when I got to a quiet location (my car). Put it into safe mode, still heard it.
I seem to be getting the similar issue as @wilson289 which is static in calls but nothing on Audio, youtube, music, etc. Only some of the stock Notification tones as well as lock screen.
Sometimes when I lock the phone the static sound lingers for 3-5 seconds.
Called in for a replacement, lets hope its ok. My device is perfect otherwise so I dont want to end up with a more crappier phone.

Any update? I think I have the same issue. Noise specially in low battery
Same issue for me. At first, I only noticed it on incoming texts/notifications. It would sound like the notification was "jammed" and was slow to come out (if that makes any sense) and it would be crackly . Then I would test it on a ringtone or video and the speakers would sound ok. The other night, I noticed a periodic white static noise coming from the phone, lasting for about 1 second and occurring every 2-3 seconds. Phone was at <10% battery at the time.

I'm on my 4th Nexus 6 and still have the same issue. My 14 day grace is over now and so if I wanted a replacement, I will probably have to do it through my device's standard 1 year warranty. I figure to wait a few months before I go in for a new one so that they will have it in stock for sure.
I had static on my first Nexus 6 but not my replacement.
Sent from my Nexus 6
Called into AT&T for a warranty replacement, they are sending me a new phone, will keep you all posted. If this 5th phone is still ****ed up, then I will just admit defeat and accept that it's a software issue... Might even get to the point of selling the phone and going the direction of the OnePlus or back to Apple (don't shoot). Will keep you all updated.
same issue for me.
sound cracks sometime (especially ringtones and notifications)
and when the battery is low (less than 15%) I have curious noise coming from the device
There is some strange noise coming from my watch. It's similar to the noise comming from headset connected to pc. Is it ok or I should start to worry?

Nope, it makes this noise constantly.
Since it has no speaker (correct me if I'm wrong) the only noise could come from your charger.
First, let others test if they hear the strange sound, too, maybe you heard it once and made it up then (no offense )
Do a factory reset (I don't think I changes something, but to be sure)
If it keeps happening, consider returning it for warranty.

Returning it to warranty is not possible. Right now I'm able to hear that sound(it comes from the bottom-right side of the watch). And factory reset didn't help.
Update: Looks like sound comes only when watch is "sleeping"
The only moving part is the vibration motor, something must be wrong / damaged if it's going off for no reason.
Sent from my SM-G900P using XDA Free mobile app
If I put the back of mine up to my ear, I can hear a faint high pitched electrical whine. I too only hear it when watch goes to ambient mode.
Some part of the power system (the watch needs to convert voltage from the battery to several different levels for the electronics & display) oscillates at frequency that is inside of the frequency range humans can hear. I don't know very much about electronics (as you can clearly tell by my explanation), but I'm pretty sure it is "expected" - that's just how it works. Many electronic devices that need to convert voltage levels do the same thing - try to put your ear close to your phone charger, for example.
Sizzling sound when awake
Hi, I have a GWR that recently came back from the LG service center because of display problems: image would continually move and sometimes
had white noise. They changed the motherboard (proven by the new Serial Number ) and it seems like working fine.
But when I put it close to my ear I started hearing a faint sizzling/buzzing sound inside it.
After playing around a little I discovered that I can only hear it when the screen in on (but not when booting up), and only when I use a watch face which displays some data not just the time. Sometimes it seems to be louder when it's connecting to the phone after it's been disconnected.
I think the sound is heard only when the watch is actively using the bluetooth connection, it's the only case that fits.
What should I do, the watch works fine, but what can this sound be ? Could it be dangerous, maybe battery related, can it explode ?
Thanks for any suggestions.
What's the serial number of your watch (you can see ti in Settings -> About)? Maybe it's related.
Mine is 502KP...
sometimes electronic devices with no moving parts generate hisses. (something like sound effect used in movies for showing electric current). i guess it's not important. you can definitely hear it on your charger too.
