Hey guys,
I am attempting to use my AT&T Tilt as a music player, but have run into a problem. When a sound file is played, there is a significant amount of distortion/amplifier hiss generated, mostly in the left channel but a small amount in the right. It can be drowned out by turning the volume up, but the volume has to get unusably loud for this to work. Turning the volume to 0 stops the hiss. This problem is present whether the sound is output through the built in speaker or headphones. Putting the phone in airplane mode did not solve the problem.
I am currently running Myn's Warm Donut, but the problem was present when running both WM6.1 and an Eclair build.
Has anyone encountered this problem before? I haven't been able to uncover any other accounts of this issue.
Thanks for any help.
I bought a Galaxy Note a month or so ago. I'm not sure if this happened before the ICS update or if it came with it as it's still all a bit new. I'm wondering if the following behaviour is a fault (hardware or otherwise), is a setting that I can alter or if it "just is".
I use the Note a lot to play music especially at night as I'm going to sleep, when I have the Note on either the quietest volume setting or something close to it. I have noticed that when the volume level is low on quiet passages in the music it drops out altogether. This is quite noticable as any background hiss (on older recordings) drops to silent then comes back in again as the music approaches a louder passage. It does the same on video.
It can be quite annoying and very distracting. If I turn the volume up (past about half way on quieter, older recordings) the problem vanishes completly so it looks like an issue with the pre-amp or DAC?
I have tried different audio players and different headphones with no change. I have also tried playing music without headphones (using the in-built speaker) and think that does it also, although it's harder to tell.
The wierd thing is googling around I can't find anyone reporting the same problem, which makes me think I possibly have a fault. Any ideas? Could someone else with a Note on ICS try the same thing and report their findings?
Test is: find somewhere very quiet. Play some quiet music on the Note and turn the volume right down until it is barely audible with the earphone pressed in. Try different pieces of music and see if the sound drops out on quieter passages - for me, it does.

I found this happening on a fade out of a song (Bjork - Play Dead). On volume 1 the sound would cut out much earlier than on volume 2. It sounds like a classic noise reduction technique kicking in - designed to reduce hiss.
Not much pop music is mixed like this any more I don't think. You'd certainly notice it more on Classical music where the dynamic range is far greater than Pop.

Perfect - yes, that describes my problem. And yes, it is classical music where I find it most noticeable (especially older recordings which tend to be quieter with quite a bit of background hiss). I wonder if there is any way to diable the noise reduction...?
Appreciate your help. At least I now know I don't have a faulty device. Massive thanks.
By the way the best answer I have so far is to play on higher sound levels and use an set of headphones with an old style (non digital) volume control to bring the sound back down to a reasonable level at the earphonesd. Pretty poor solution really - had hoped for better from my lovely new Note.
+1 big problem for my...and now...not solutions...waiting...
I have this issue since Samsung replaced my mainboard. It happens on stock ICS and CM9. I haven't tried Gingerbread.
Could this be a hardware problem?
Is there any fix to this yet, this is exactly my problem, good tip about using an in-line headphone volume control though
The same bug. Please fix it somebody.
I too have this problem with my new Galaxy Note (ICS 4.0.4). I'd be interested to hear from any Note users that *do not* have this problem when playing back audio at low volumes. If you don't notice the audio completely dropping out, please list what version of Android you're running. Thanks!
I guess we need some more experimentation to see if it's a hardware or software issue (or both).

Hi,
I am quite sure this is a software bug. When my note was using gingerbread, it was OK. It started to behave this wasy after the (official) ICS upgrade. Some of my friends are using unofficial ROMs (4.0.3 or 4.0.4) and it is ok - I tested it. So my conclusion is that samsung put some software trying to reduce noise in low audio volume, but it's not working as it should be...
More people are stumbling upon this noise gate problem:
http://code.google.com/p/android/issues/detail?id=35861
http://forum.xda-developers.com/showthread.php?t=1717425
I experience it on ICS and also on CM9, only with headphones plugged in (not when listening to music via bluetooth on the Sony MW600).
It does not occur on Gingerbread, but I don't like to use that ROM as a daily driver...
Can anyone confirm if there are custom ROMS that do not have this behavior?
Or is there maybe some way to replace the ICS media playback service with the GB one?
Well, all ICS-based custom ROMs I've tried suffer the same irritating behavior.
And it also turns out that GB has the same kind of noise gate, but the threshold seems to be a lot lower and therefore it doesn't kick in that often.
But I've just installed a CM10 nightly, and that seems to solve the issue.
my 2 cents
I can confirm, that I have similar problem.
I have the problems only when watching movies. the sound just cuts off when the character stops speaking, so it cuts off the background sound.
I tried different kernels, ROM´s... same problems on GB, ICS, CM9...
I have a hillBilly solution that works for me! When ever the sound cutting starts, I just change the volume for one level. The cutting will off course repeat... but it's indeed better than listen to the clipping...
For black clipping I use highest brightness and film screen mode. It does the trick for me...
But it just pisses me of when I realize that I have the phone with ****ty screen, sound and bricking danger...
wtf sammy... i just cant belive that i paid 540 eur for this, its sad

This is bugging me too.
Would this be something controlled by the kernel?

Just flashed latest PA, and its till there!
Im not an expert! Does anyone remember a background noise reduction option while making a call in GB??
I cant find it in ICS or PA. I think that this background noise redustion system is causing the cutting. It must be somehow connected.... im not an dev or anything but my gut tells me that this could be!
anyone?
Take care

OK all, let's figure out what ROMs don't have this problem, and start bugging the Devs to try to fix it on the others :laugh:
Well, I just noticed that the sound cut-off is also back on the unofficial 08/31 build of CM10. It was much less noticeable on the 08/28 build. :crying:
The difference between the two builds is a huge decrease in sound volume: build 08/28 was much louder than the latest one. Maybe the noise gate simply doesn't kick in so soon when the system volume is cranked up. You basically get the same effect when turning up the volume completely and turn it down with an inline analog control - as suggested by StarFishUK in post #3.
So my question would be what makes the volume louder on 08/28?
And how can I get that 'cranked up volume' on newer CM10 builds or preferably on ICS roms? Any ideas?
By the way, I totally agree with your 2 cents DonLaDroid. I never had this much trouble with my old Dell Streak...
Haven't noticed this myself (CM10), but i've noticed something incredible annoying in CM builds, and that's when i'm listening to music with headsets and i'm increasing the volume, it seems that it's "missing" a couple of steps. So when i'm increasing the volume it'll go from 5 to 8 in one step, and not 1,2,3,4,5,6,7,8,
It should be: 0,1,2,3,4,5,6,7,8
But it is: 0,1,2,3,4,5,8
How to test this problem. ..
Go to a quiet room.
Set audio level to one (one click up from silence)
Play some music with soft passages.
For me, the sound shuts off during quiet audio for speaker and wired headset. Note that this isn't simply an absence of sound. The sound turns off then suddenly starts again in the middle of a louder passage.
Bluetooth doesn't have the problem.
A gentleman on one of the Kernel threads believes this may be a hardware issue. The sound clips to cover noise from the speaker.
All, it seems that this is a "feature" of our phone. We will need to contact Samsung for the word on if this is a hardware issue or of it can be fixed via software. Right now it seems this happens in all ROMs, Touchwiz or AOSP.
Workaround is to use Bluetooth or a wired headset with an analog volume control.
I am experiencing the intensely annoying sound cut out bug. This appears to occur under the following circumstances
1. Headphones plugged in only (not speakers or blue tooth)
2. The phone volume is fairly low 1-3
3. Music / Video is playing and there is a quiet passage e.g. music fading out, whispering in a film, sharp drop in volume of a song
The effect is that rather than playing the sound the sound completely cuts out.
My current suspicion is that it is something like a headphone amplifier power saving measure. Essentially cutting off the sound amplification if the system believes just white noise / hiss is coming through the headphones.
I have tons of music that triggers this issue (only permanently up tempo music such as dance and most pop do not trigger this issue), I have tested in Cyanogen, PA & SlimBean. Others have reported this issue in Stock ICS.
Does anyone know if the current Stock Samsung has this issue or not, before I attempt to get support from Samsung who presumably have done all their audio testing with Gungam Style and therefore have managed to miss this massive issue?
Been asking for a fix for this issue for ages, I'm either being ignored or nobody has a fix, thus can't be fixed.

Sadly there's no real solution to this annoying 'noise gate' problem, which I've noticed since ICS on every Stock or Custom Rom that I have tried on the N7000.
The issue is also discussed here: http://code.google.com/p/android/issues/detail?id=35861
For now, you only have two workaround options:
1. Get a pair of headphones with inline analog volume control. Crank up the volume on your device and lower it within the headphones.
2. Program a Tasker profile to play an inaudible sound that keeps the noise gate open (http://forum.xda-developers.com/showpost.php?p=35047527&postcount=25)
I've used option 2 before, but decided a few weeks ago to switch to 1 (with the Sennheiser CX 400-II).
Also I've noticed that the problem does not occur when streaming media audio via Bluetooth.
This is good advice, I have an inline seinheisser controls somewhere

Hi - I have this problem too and so do many others.
To my ears, it sounds like there is a noise gate being used on the headphone output to mask off system noise at low levels. Noise gates will close when audio drops below a certain threshold and you can use them to eliminate background noise during periods of silence in music. However, in this instance, it shuts down during quiet passages - especially when listening to classical tracks with a wide dynamic range.
IF it is a noise gate, it is likely to be implemented in the hardware (doing it in firmware wouldn't mask noise generated by the phones circuitry - which is he whole point). Consequently, there might not be anything that can be done to resolve the problem. However, it is possible that the phones firmware configures the audio chip during boot-up. This being the case, an industrious programmer might be able to do a few tweaks and disable or modify the behaviour of the gate. I hope so because all my music is on my Galaxy Note and it is painful to listen to at times!
That's the real reason I am here: is there anyone on this forum who knows enough to be able to write a fix for this as it appears that Samsung aren't listening? Some people report this problem on the Note 2 as well.

Damn it -- sorry to hear that about the Note 2, as I was thinking of upgrading to that. Hopefully the Note 3 will have it fixed, or I just might have to go to the S4
Yes, this bugs me immensely -- it affects music with soft passages (classical) at any volume level, and of course is irritating when listening to music at night. What I'd like to do is to find or make a headset or cord that supports the microphone and includes an analog volume control.
My N7000 has also this problem with every kernel and rom I tried. With Android 2.3.6 and 4.0 it was only happening with the videos, but after 4.1, it happens with the music too. So I think it can be fixed by software (I mean actually fixed, not the inaudible sound solution).
It's very annoying, I bought the note fot its big screen, to watch videos and now I can't do it because the sound sucks. Also I can't lisent to music anymore in the night...
Solution for annoying noise suppression!
This seems to be the solution:
Start 'phone', go into settings, and disable 'noise suppression'!
Seems to be working...
There is a patch that fixes the problem for my N7000 with OmniROM:
github.com gustavoss android_kernel_samsung_smdk4412 commit 3019675d57c4046c30f82d04ce41913150df0d6e
(Sorry for the distorted link, as a new user I am not allowed to post links yet...)
The question is: How to get it into CM, OmniROM, and co.?

This problem has been reported on the Samsung Galaxy Note, S II, Droid DNA and others, but I didn't know it was also a problem on the HTC First until I got mine. Whenever my music goes to a low volume with my headphones on, the sound just mutes. It comes back when the music goes louder. If I increase my volume, it cuts off less. At full volume, it does not cut out at all. I have no problems playing through the speakers.
One needs to listen to audio with short silences to be able to notice it. Some say it is related to Beats Audio, with the problem going away if Beats Audio is turned off; I don't think that is a possibility on the HTC First, though.
I use my phone mostly to listen to music and streaming radio, so this is a deal breaker for me. Are any of you experiencing the same problem?
i can not confirm the problem.
i tested my HTC with BOSE and Pioneer headphones and do not have any problems with both.
no matter if i play music loud or very low volume.
will test it tomorrow with my monster beats and let u know.
HTC Support on Sound Cut-Off Issue
For the sake of completeness, I will let you know that I called HTC Support about this sound cut-off issue. The person on the phone was very nice and tried to help me for some 40 minutes.
The bottom line is that he couldn't reproduce the issue in the few songs he played (which didn't surprise me). He made some note for the developers but I don't think anything will come out of it.
In the meantime, I found a good song to test this strange behavior: "brainstew" by Green Day. Plug your headphones to your HTC First and listen to the first 30 seconds at low volume. It you hear distortion as the sound volume changes, please let me know (right now it seems that I'm the only one noticing this).
Thanks!
I'm seeing this as well. Has nobody else seen this?
