Android kernel codec driver porting - General Topics

I'm looking for someone who can fix an audio problem on my Samsung tab 8.9. this tablet has an outdated android version "3.2" and It's the Chinese model sch-739. I searched on XDA in the hopes of finding a custom rom that will give it some new life but found nothing for my specific model, however, I've found custom roms for the global model "gt-p7300" of the same table. I flashed them on my Chinese tab and they boot up and work good except for audio and a few minor issues. after digging into the audio problem, we found out that the audio codec driver " wm8994" does not load when flashing P7300 firmware on my china P739 tab. after further testing, it turned out to be a kernel issue because flashing "original" p739 kernel on p7300 firmware got the audio to work. we already contacted Samsung and they gave us kernel sources for P739. so the job is to port P739 audio drivers to p7300 kernel so that audio works on p7300 roms...my budget is set to 200 USD

[Q] Roms compatible with Sharp FX plus? (ASD1)

Hello XDA,
I have bought a new android device for myself today, the Sharp FX Plus (Model: ADS1) and I've been browsing on the site to find some compatible roms; But no luck. I've used the forums before to successfully root and put a rom on my ASUS tablet with no issues, but this one is a mystery. Is there a thread with what roms are compatible with my phone or has nobody ever really looked into this phone? I've tried to google it with no luck, either. The phone is already rooted, I got that far, I just can't find any roms that are 'confirmed' compatible with it.
Thanks to whoever replies!
P.S. I'm slightly new to the whole custom rom thing - but I do somewhat understand the basics.
metoo!
I too have a sharp fx plus ads1. I have my phone rooted but am having no luck finding a custom rom. I understand it is kind of an entry level android and maybe out of date but it has all the capabilites I need. I also know enough to root my phone and install a rom but not good enough to actually create my own custom rom. Is there anyone that has the time and enjoys doing so that would help out with a custom rom for these phones? I found a page that mentioned updated to 3.2 with a new rom but there was no link for the rom so I'm thinkning it was a fake. Any help or suggestions would be appreciated.

EDIT: I posted in Misc Android Development section here, trying to put the information in a centralized area for any potential development on this device.
Recompiled the CM7 Kernel as a test using the device's config.gz, working on getting the CM7 source to go (its being tricky lol). I have a test CyanogenMod 6.1.2 ported from a Z71 that runs, as well as a modded stock 2.2.2 ROM. A "dirty-port" test of a Z71 CM7 rom boots with some mods (no radio, networking, etc..) - so there may be some hope for this lil thing!
Hope that helps

[Q] Custom Rom Audio Codecs?

First time custom ROM flasher here,
I am running the Google Edition 4.4.2 ROM by danvdh for the T-Mobile Galaxy S4 (SGH-M919)
ROM thread here: http://forum.xda-developers.com/showthread.php?t=2539361
I have noticed now that I am running this ROM I cannot play WMA audio files. I've never heard of audio codecs for mobile phones, but if this same issue were occurring on my PC, it would be the first thing to come to mind.
Do I need to install some codecs? If so, which codec packages do people recommend?
Thanks in advance for any responses.

[Completed] [Q] Need help on CM12 ROM

Last month I'm trying to build my own CM12 for GT-I9060 Samsung Grand Neo device. I have built it successfully (with pawitp i9082 compat patches) and flashed it to my device. Everything seems to work great, Wifi, camera, etc. Baseband version was recognized too, and I got my signal. However I didn't get any mobile data, even if I change the APN type. Another problem was during the call I didn't get any sound at all. There must be something wrong with incall audio, but I don't know how to fix it. Can someone guide me which file or how do I fix it?
Here's the link to radio logcat: pastebin.com/8CgGM7Lg and pastebin.com/bic27Rwk
and here's the main logcat pastebin.com/MmAASyLR
Thanks in advance!
Your best bet is to ask your question here and also realize that you have synced the nightly repo which is prone to bugs and that if your device is not officially supported you will continue to encounter them
Good luck

[Completed] Custom Huawei U8666E Fusion 2 rom Bluetooth error

So I decided to take my old AT&T Fusion 2 and upgrade it to android 4.0.3. I installed clockworkmod 6 and flashed the ProFusion rom with CyanogenMod 10.1. All went well, but bluetooth isn't working and the site that the rom originally came from, no longer exists so the bluetooth fix method that is used to fix the issue isn't available for download. Is there a way (and I'm new to android development, but willing to take any steps necessary) to rewrite the bluetooth code so that my phone is compatible with bluetooth again? This rom is the only rom compatible with my phone

Hi,
Thank you for using XDA assist
It looks like there is no dedicated forum for your device. However there is a general forum for android here http://forum.xda-developers.com/android/help where you can try to ask to get the expert's help
Good luck.

Help fixing audio problems

Hello, im kinda new to developing and fixing bugs for new phones, i am trying to port a rom from the nubia z7 max(nx505j) to the nubia z7(nx506j) and i got most stuff working, except for the audio. Im using the original mixer_paths.xml in my build as most of the original audio policies. Where i am stumped is the audio_platform_info.xml, i cannot find this file in the stock rom, and the one from the nx505j device tree cannot help with the problem. Could any seasoned developer help with bringing up this file for a new device? Audio works in headphones, therefore its most likely a configuration issue getting it to work in speakers and microphones.
