Flakey audio?

It seems the NookColor's audio subsystem is pretty flakey. For one thing, I notice a big lag in audio and video when playing them (rockplayer, youtube and others). Also, from time to time, sound will just die on me totally and only way to get it back is to reboot the nook.
anyone else seeing this?

If the audio is dieing after the device goes to sleep, this appears to be a defect in certain batches. I had this problem (even after hard resets), but exchanging it out for another took care of it for me.

i'm able to get it back by re-starting the NC.. sucks... maybe i need exchange my NC... again... the 1st one had a bad microUSB port

called tech support & they ack. that this is a problem.. thanks...

Doesn't seem to have enough output; the overall volume level seems to be very low. Everything else seems fine, so far.

crappy mono speaker will do that for you

No sound at all

So, about 24h ago, my phone lost the ability to dispense and intake sound. Just like that. A peculiar thing is that only audio jack works.
I didn't drop it or hit it or damaged it in any way, nor did anyone else, the phone was with me all the time. It just stopped playing the sound whether it's a ringing or sms or a notif of any kind. Music don't play on speaker, and when a call happens, there is absolutely no sound on either end of the line.
I did a factory reset and a V20b reflash and everything else and... nothing helped
Is it a hardware fault?

looks like a hardware fault to me, but it could be something pretty simple. It sounds like your saying the mic died also? this would narrow the issue down if so.

Did you have headphones plugged in before the issue?

Yes, the mic died, too, because when called, the person on the other end gets no sound whatsoever from my part. It's the same the other way around, which is strange since the mic and ear speaker are on the opposite sides of the phone. What takes out both of them + the main speaker?
I recorded a film with camera while a moderate music played in the room, but there's nothing but crackling.

Yes, maybe 3 hours before I noticed the problem the first time. I listened to music while outside.
If you're aiming at the phone thinks it has earphones always connected, it's not that. The phone clearly registers when they are plugged in and when they aren't by displaying, or not, the earphones icon in the notifbar.

Sounds like a weired issue to me. Once it happened, did you reboot the phone after this isue occured?
If I remember correctly, my old phone (not this one) had exactly same issue, I think rebooting and clearing cache and stuff (not sure if factory reset) fixed the issue. Worth a shot before going to fix the hardware

It's happened to me many times on my last Sony phone. Just keep jamming the headphones in and out and it should clear, the phone still thinks they're plugged in

Yes, a few times. Factory reset and V20b reflash, too (It was on official 4.1.2 anyway), and wiped all the partitions from boot menu.

As I stated in my previous post, phone detects the headphones the normal way when they are plugged in and displays the headphones icon in notification bar, and removes it when I pull them out. Furthermore, music players pause/stop playing the moment the phones are unplugged.

Thanks, I'll have a look, but I'm not really sure what I can or should do.
The thing is, the phone is under a year old and has warranty, so I elect not to open it by myself... yet. Just don't want to leave it at the shop where it'll most certainly spend at least 10 days before anyone even looks at it (because of Easter and International Workers' Day). I'm also baffled by the fact that the ear speaker on top of the phone doesn't work. If it were just the bottom part, I would've gotten a replacement and switched it myself (one part holds both), but it's obviously something more complicated than that and I don't dare to discover what on my own.
In any case, I'll see what I can do about the problem after the holidays and I'll keep you apprised of the outcome.

Epilogue: The motherboard was faulty and they gave me a new phone.

High pitched noise

Hello,
My Optimus 4X HD outputs a strange high pitched Noise from the headphone output. It basically sounds exactly like coil whine from a graphics card would sound like. I tried plugging it into 3 different amplifiers to check if its really my phone or the amp i was using but turns out its my phone (I also tried my brothers ipod on the same amp with the same cable and the noise was gone). I am running the latest nightly of CM11 and have no apps or tweaks installed which would alter anything sound-related. This is really annoying especially when there is no music playing, can anybody help me?

Three ways:
It's a ROM-related issue. This means every CM11's user - at least on our X3 - should experience that: in my case, I'm not experiencing it, yet. You could make a test, by switching to another ROM, checking if the annoyance is still there.
It's a phone-related issue. This means your phone has a manufacturing defect or something got broken.
Your headsets are broken, instead. You could try them on another platform.

I have exactly the same issue, no matter which ROM do I use, gotta live with that

Turns out the cause of this is the crappy audio chip of the LG, it produces interference noises when the impedance of the amp/device you are plugging it into is higher than 100 ohms.. thats also why it doesnt appear when using headphones as those usually have a lower impedance (mine have 32 ohms for example)...

[Q] Strange noise

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.

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.

Sound bug! anyone have it?!

So, i have run this issue since the day i have the phone, but lately is gettin annoying, when i listen to music trough earphones (wired ones, i dont have tested bluetooth but i think it will be the same) and open a game and have silent all game sounds and music, or facebook in web browser and autoplay came in videos that the sound of my earphones get low, like 20% to 30% lower than the max of the phone can output.
Like, open music, playing at max volume, open a game with all sounds silent and boom, music volume gets a cut about 20 to 30% and the graphic say it was at max. And when exit the game, volume still have a cut, i need to fully close the app in recent apps open and then the full volume is restored.
how to fix this?! i think isnt a music app setting, cause i use the default Mi Music app and dont see setting to fix this, even isnt a game option cause i run all my games in silent.
are any other setting in system setting to fix this?!
im on latest v10.2.30 and rooted with magisk.

game booster is disabled on my device, and deleted too from the root system folder so, it isnt the problem here.

Try listening to music on any app at Max volume. Does it happen too ? I have a similar problem but it happens all the time. I just have to raise volume past 75% or so and it starts to click. Sometimes i get audio just in the left earpiece and sometimes it just cuts the audio to like .. 5% of its maximum ( even though it's at Max) .. i was thinking it can be an ohm limit with the stock USB c to Jack as via Bluetooth there's no audio problems at all

Your problem is most likely damage done to the wires through which data travels to the earpiece, damage that occurs near the 3.5mm jack or maybe your adapter got twisted too much though I'm pretty sure it's the earphones' cable that's been bent too much, happens with pretty much every earphones no matter how gentle you are. You can check by gently twisting the part of the cable that's close to the jack and see if sound comes and goes in the right channel. It's very hard to fix unless the damage is close to the 3.5mm jack(where it bends the most), then you have to cut the jack and the cable up to the part that's disrupted including it, buy a new jack that's similar to the one you just cut(that has microphone contact and buttons contact for example) and attach the wires properly and glue/tape the damn thing. Not that easy to do either and requires a person with a bit of electrical know-how.

I own a pretty much "new " Mee audio m6pro 2nd gen. and there's no problem at all with them. Just when I'm using them on my also new mi9 . And if i twist the USB c Dongle to check if there's some cutted wires there's no problem, but as soon as i reach high volumes the audio starts to click, fade or simply clicks and just the right or left earpiece keeps sounding with a very clicky sound and distorted. Maybe the bundled Dongle came faulty. Worth to mention that I've used the same earphones at a very much high volume with a creative soundblaster soundcard on my pc and there's no click nor distort.

Not really the problem cause i have done the test with 2 adapters and 3 pairs of headphones/earphones and all new and well conserved nothing twisted or broken and even that way i get the sound cut ONLY when open a game and are listening to music, the problem is fixed ONLY when exit the game and close it on recent apps, the volume are restored when doing that, everytime.
So, i think is a Miui issue, maybe sound priority or something like that, but even...i have silented the sounds on game, this shouldnt occur, but it does.

Well my reply was to Vichergsen because what he described is pretty much what happens when a channel's wire gets disrupted, at least if I understand what he said correctly. I didn't mean to address your issue because yours is definitely a software issue so besides waiting for a fix there's not much I can advise. I also seem to encounter a strange issue when I listen to music, say I set the volume to a level, and if I use certain apps for some reason the sound gets louder than it was before using them, almost louder by +2 I think even though the volume level remains unchanged.(miui 10.2.30)

Guess it's worth to mention. My bug was caused by dsam mod ( stereo for speakers) .. never thought of it cuz i was pretty sure it was only directioning audio to the earpiece and not increasing headphones gain lol... Although after disabling that module i no longer have the " Hi-Fi sound" on sound settings welp, i guess I'll stick with tidal's master quality and flat audio. That should be enough for a Smartphone
