How to make audio working in kernel from code.google.com

Hi,
I have BB Rev.C2 board and u-boot,x-load and kernel sources from
http://code.google.com/p/beagleboard/wiki/BeagleSourceCode
Tool chain installed is 2007q3 from CodeSourcery.
I am newbie to OMAP and BB.
I would like to develop a simple application that can play wav file or
small amount of predefined data from buffer.
Could you please help me
1. what are the options I have to select in kernel with " make
menuconfig "
2. Is there any driver available in kernel
3. what is driver and where it is in kernel
4. Is there any guidelines/ docs available for audio codec to use
5. what are the things to be done in application and kernel

Thanks in advance

Hi Khasim,
u-boot,x-load and kernel sources I have downloaded from
http://code.google.com/p/beagleboard/wiki/BeagleSourceCode .
Not from git links given in http://code.google.com/p/beagleboard/wiki/BeagleboardRevCValidation
.

Is default configuration enough for enabling audio drivers in the
above kernel from http://code.google.com/p/beagleboard/wiki/BeagleSourceCode
??
or
do I need to do some thing else ??

It would be more helpful for me if you can clarify my doubts mentioned
in the previous mail.

Thanks in advance.

I could not hear any sound from recorded file for audio IN test on BB.
Also checked playback of recorded file in PC but there also no sound.
What could be the problem?

http://code.google.com/p/beagleboard/wiki/BeagleboardRevCValidation
also contains pre-built images for u-boot xloader and kernel, I
suggest you use these instead of old one.

Yes, default config is good enough for Audio in/out drivers.

Hi,

I downloaded pre-built images for validation from
http://code.google.com/p/beagleboard/wiki/BeagleboardRevCValidation.
I followed the instructions given in the above link. I tried to
validate Audio-In and Audio-Out in BB but I did not hear audio from
Audio-Out line of BB but it is only noise sound.
Of course I also tried the recorded file play in PC but nothing
audible it is only noise...

I have connected the UART cable to PC, SDcard to BB, Audio-In cable
from PC and Audio-Out to self powered speakers.
Then I connected USB cable from OTG port of BB to Host port of PC
while pressing USER button and I followed the instructions given in
the above link.
Also I would like to have sources of pre-built images and kindly tell
me
1. how I can get those sources from windows PC ( some of the links
given are not active)
http://git.gitorious.org/x-load-omap3/mainline.git
http://git.gitorious.org/beagleboard/mainline.git
2. guide to build the sources
3. Can I use same toolchain arm-2007q3-51-arm-none-linux-gnueabi-i686-
pc-linux-gnu.tar.bz2 form codesourcery ? if any any other pls mention

TIA
