USB speaker stereo output problem (one side not working) - Moto G Q&A, Help & Troubleshooting

it was working good few days ago. now one speaker (left/right) is not sounding when i flashed a custom rom for test purpose (may be CM based). now um on AOSP based rom (5.1.1). but from the flash my usb speaker sounds only one side. after that i switched and flashed several custom rom but no solution. plz help me. i think its not for roms fault, because roms works correctly before .
is it kernel related problem? or something??
can flash of factory rom may bring solution?
device : moto g (xt1033)

A problem with speakers hissing.

Hello xda, first of all i am sorry for my mistakes - english is not my native language.
I got nexus 5 about month ago and started flashing, rooting , instaling custom roms, karnels... And yesterday i find out after installing slim rom and elementalx karnel that my speaker started hissing in low sound ( no mater if its from poweramp or youtube). Then i flashed into stock rom, but hissing is still here :/ also tried carbon rom with multi rom and hissing didn't disappear.
So is there any solutions? Or this is hardware problem ?

[Q] Keyboard typing lags only in certain roms (KitKat) Please help

Hello
When I bought the oneplus it was shipped with cm11s an I had not a single problem with Touchscreen or keyboard. I changed the romd , tried all kinds of.
No I am facing a keyboard input problem with all kitkat roms. I want to try miui or cos but with all of them I get the same result: can't type fast the keyboards are kind of slow and laggy...
I tried everything.
I tried different original cm 11 roms and different firmwares and touch problem exists. With lollipop ROMs 5.0 or 5.1 no problem
Any idea would be appreciated
Thx guys
Any idea ?
It is not hardware related. For example.. It works right now with exodus ROM like a charm..
Do I need maybe a 4.4 modem ? Something else?
Anybody ?

Pressy, Klick!, Xiaomi Mikey button & CM12 ?

Hi all,
first of all, my problem is related to Moto G 4G (peregrine model), i don't know if (but it is probably) this occur with Falcon.
I bought a clone of pressy button (http://forum.xda-developers.com/showthread.php?t=2742665) and i'm pretty happy with it on stock rom, i can answer call with one click and launch torch with a long press on it.
The strange thing is that it doesn't work on any custom rom i tried, i tried with all available apps, but none handles the clicks as it should, so i assume there's something to do with CM 12, maybe it is missing some drivers that are present in stock rom ?
I should downgrade to CM11 to see if it's working or not... i'll tell you later.
Does anybody use such a thing and got it working on a custom rom ?
Any help would be greatly appreciated, thank you and have a great day.

Help in fixing bugs

I came across custom rom port for Intex Aqua star 2, and half successfully ported it to my own Spredtrum 7731 device, using stock rom as base.
The port works perfectly,except for the fact that it produces no sounds through the loudspeaker. Headphones are alright, no problem making and receiving calls, but no ringtones or any other sound that should be played through the back speaker.
I would appreciate some help figuring out what I have to replace from the Stock rom to the Custom rom in order to fix this...
(by the way, the same thing happens with any other custom rom I ported... no other problems apart from that...)
Thank you in advance.
P.S-I forgot to mention I have already tried replacing lib files including "libaudio" in the filename.
I also tried replacing lib/hw/audio.primary.default, which also made no difference...
Here is my logcat

Click to expand...
Click to collapse
Try backing up your data and then clean flashing. I'm on 3/25 too and don't have any issues with calls.
Already tried many times but doesn't work.... I'm starting thinking that i have the mic broken...if i enable the speaker the problem doesn't persist.... The strange thing is that with stock firmware works perfect
