[Q] [CM 9] Sound distortion when volume is high. - Sony Xperia P, U, Sola, Go

Hi,
I'm trying to figure out how to avoid problems with sound quality at high volume levels. I noticed strange sound artifacts (high quality headphones)
so i decided to test with udial-sample (you can find it on hydrogenaudio forums) and with maximum volume sound is very distorted (It was not present in original firmware).
Another question - which library is responsible for sound resampling and how to configure it (resample method)?

Very Low Media Audio

I'm coming from a D1 and was used to its speaker volume. I've noticed that in most all apps (skype, youtube, sirius xm) my Tbolt's output volume is pretty low. I've got the slider up as high as it goes, and it doesn't come close to the output of my last phone. Is this something with the ROM I'm running? Are people with stock phone's noticing the same problem? Is there a setting I'm missing?
Thanks
Did you change the media volume in sound settings or just the overall volume of the phone?

Jb audio quality

Anyone notice a decrease in the audio quality and volume when switching to jb.? The volumes are low especially in call and ring. I was looking at the acid mod-any suggestions...

[Q] How many S3 users get low-level background hiss with audio playback?

I bought my Galaxy S3 (UK version) when they first came out, but recently had to have the motherboard replaced under warranty due to the phone suffering from Sudden Death.
Before the repair, the audio output via my earbud headset was perfect, but now I'm getting a persistent and annoying low-level background hiss. This is not affected in the slightest by the volume control - even at the lowest volume setting the hiss is still present at the same level. It lasts for about 4 seconds after audio playback has finished, and then stops with a slight click/pop as the audio circuit shuts down.
You can also hear it from the rear-panel speaker if you put it close to your ear and perform any action which causes a noise to be generated - e.g. keypress clicks or the notification tones when you press the volume rocker (just make sure volume is set low first though, as that speaker can be loud when you've got your ear up against it!)
I've done some checking and it's definitely hardware related - nandroid restoring my old ROM doesn't make any difference. It is really annoying when I'm listening to music at night in bed, usually at the lowest volume setting, as the hiss is much more noticeable without other ambient noises to drown it out.
There were a number of reports of similar issues last year but not everyone seemed to be affected, and the threads all seem to have dried up now. I'm wondering how many 'original' S3 users have this problem, versus more recent purchasers? I've added a poll, just to see how widespread this issue is - please treat any phone where the motherboard has been replaced for Sudden Death issues as a 'recent' phone.
And how do I go about getting it fixed if the current motherboards all seem to have the same fault? Is there any low-level firmware setting to reduce the physical gain of the internal audio amp circuit, as it does seem to be happening in the final stages of audio output rather than in the software-controlled stuff? I'm not worried about losing the top end of the volume range, I use bluetooth for more amplified playback anyway.

Background hiss / noise no and thats from one of the very first SGS3 .
But a fair number of the sound mods do add noise .

That has been well posted up on XDA hiss + pop click on shutdown as you said long time ago .|Not seen any user posting really since those threads died . Most are just looking for more loud or more boom boom .
A number of kernels now have sound adaptations .

Yeah, I first put it down to some sort of audio mod in the ROM that I had installed, so I nandroided back to the vanilla JB that was in the phone when I picked it back up from repair, and even back to my older ICS stock ROM (which had no audio mods at all) and they were all exactly the same.
Sound tweaks are all going to effect the source sound digitally, before it hits the analogue amp stage, and I suspect it's the final analogue stage which is generating the interference.
I don't care for lots of volume or boom boom (and anyway, I have amplifiers or car audio for that) but I do want my original lovely hissless audio quality back...

Do you still get the hissing with a good sound enhancing kernel (such as boeffla)? If you do, sounds like you have a hardware problem

Ah, I didn't know some kernels were better than others for noise reduction. Although I'm not so interested in 'enhancing' per se, more reducing! But the problem I'm getting is not effected by the volume controls at all, the hiss remains constant whatever any of the level sliders are set to, just as long as the audio circuits are enabled.
The ROM I'm currently running is Omega AOKP v7.0, which is based on AOKP JB 4.2.2 milestone-1 and stock kernel. Is there a suitable kernel compatible with that which might help me does anyone know? (boeffla isn't as far as I can tell)

My SGS3 is about 9 months old, and I have this too. However, in my case the background hiss is at an extremely low level - to all practical intents it's inaudible. Certainly not enough to be annoying, even in the quietest of environments.

Stereo sound mod - need help with balancing the volumes

I've recently made a mod for my device managing to enable the earpiece/speakerphone during media playback and turning my phone into a stereo capable device. However, as expected, the earpiece won't sound as loud as the main speaker. I tweaked the gains but it's not enough.
What i am trying to create is a modification that will make a point of intersection where both the earpiece and the main speaker have the same loudness. After that point, the phonespeaker will remain at its maximum volume and the main speaker will keep up with the media volume slider.
There would be one simple way to double the earpiece gain or triple it or finding a certain level that matches the loudness of the main speaker until a certain point but the main issue is that the media volume slider will keep adjusting the loudness of the earpiece, making a lot of distortion afterwards.
I need someone to explain me how to disable media volume control for the earpiece after a certain media volume level, thank you.
Yet another way to satisfy my needs is setting the default volume level of the earpiece to maximum, or at least creating only 2 levels, first which is mute, and the second which is max, no matter the media volume level, i don't know how to do that either.

Question: is possible to get earpiece speaker volume? (root)

Hi all,
I'd like to know if it's possible to improve the earpiece speaker volume on pocophone. In combination with main speaker sounds so loud, for example playing a video, but when I hear a voice note or a call, it's low. In other phones you can edit some values in mixer_paths.xml (vendor/etc) being root, but I tried unsuccessfully.
Any help would be appreciate. I use lastet MIUI global stable 10.3.8.0
Thanks!
if your device is ROOTED (as you say) and the kernel you are on; having SOUND mode ( franco, Twisted, Optimus Drunk) then from SMARTPACK kernel manager ( Download here ) you can change incall and earpeace volumes.
There is no speaker volume thou!
