[Q] Significant Amplifier Hiss During Music Playback - Tilt, TyTN II, MDA Vario III General

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.

[Q] Background noice when playing music

I have noticed some background noice when I play audio files in the music player.
I know from this thread that other people have the same problem but I have not been able to find a seperat thread that cover this.
forum.xda-developers.com/showthread.php?t=735918
The problem is easy to hear if you play music through the build in loudspeaker and then turn the volume to 0 while the music is playing. I have notice that when I pause the music the noice will continue for about 2 sec followed by a "click" and then the background noice will disapear (probaly because the device is going to some powersaving mode).
The problem remains with all the headsets I have tryed and are pressent on firmware jm7 and jm8.
Anyone noticed the same problem and more important do anyone have a solution to this problem?
unable to reproduce
i do play music from the building speaker quite a bit, as i keep testing music for my alerts anc custom alerts for each contact
Hi there,
I had this problem also... was playing with the TV out. Once I turned this off the problem disappeared. Have you tried the standard issue headphones... this might also be part of it, Samsung is using a different pin setup
that makes more sense go into settings and make sure the TV Out option is disabled, if you leave it on, it can interfere with the audio output
i recall this being discussed on another topic a while back
try unplugging the usb cable if it's connected...

[Q] Low sound cut off

Hi all,
I've been noticing recently that when I'm playing music through a wired headset the sound gets muted if the volume goes very low. When the music gets louder it comes back again. The effect sounds like a noise gate or limiter being applied.
Searching the web I found a page with similar complaints which seem to show that this is unique to the Galaxy Note with ICS.
Is this a known problem?
Cheers,
Paul
I have same problem. Anyone have proper fix for this problem?

[Q] Sound cut out bug on low volumes?

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.?
Also see:

Kind regards

Strange speaker issue

My mi3 is only 5days old . it's running Android 4.4
MIUI version 4.12.5(beta)
When I'm playing music from the speaker it makes a strange buzzing noise. Even the ring tone makes same kind of noise. But if I play music with power amp it's almost unnoticeable. If I turn the speaker on while on FM radio also the buzzing notice becomes unnoticeable and sound is clear. Wonder this is a hardware issue or software issue. Anybody else facing the same issue?
It was found out to be a blown out speaker. I got a replacement with the warrenty.

Nexus 6 Speaker Issues

Hi everyone, I have some speaker issues in my n6. The front dual speakers are fantastic and hands down the best I have ever used in any smartphone, but whenever my phone's battery level drops below 70%, the speaker volume automatically decreases, without me having to manually lower don the volume.
Whenever this thing happens with me , I immediately check the volume panel and there it says that its already max. Then when the phone's battery level drop to around 30%, the speaker volume decreases significantly as if I am listening to at half the volume and the volume panel still shows the volume to be at the max.
At first I thought, it must be a hardware issue, but that wasn't the case. when i watch videos on MX player, this problem doesn't seem to occur at all even if the battery is less than 10%. This problem only occurs whenever I use a music player. Earlier I used google play music, then I changed to sony walkman and I have also tried various other music players from the playstore as well but the problem always persists.
I even changed my roms for months , but still no luck.
My question to you guys is, does it happen with anyone else? How can I fix this issue if its not common?
Your help will be appreciated
