Hi,
I have BB Rev C2 board. 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.

Can you run the mplayer DVI test, it should play audio as well. This
should confirm your audio out support.

Yes it is ramdisk.gz, this has all the utilities to test the beagleboard.
Can you please suggest me whether I can use these sources for
startup??
If you want to validate the board and setup and want a simple rootfs
to work on, then go for the ramdisk image (it's again based on
Angstrom / OE but with limited features for reduced size). If you are
looking for more UI, DSP, SGX, etc then OE / Angstrom build has
support for these components and has been tried on Beagle.
May I know why is not able to test Audio-In and Audio-Out test?
I think this is problem with your line in setup or the way you are
recording the audio. Please double check this one.
I double checked it but not figure out the problem.
What is special setup I need to do?
If I play any song in PC I an hear that from head phones connected. I
am connecting Line-In cable one side to PC's slot(head phone symbol
will be there) where I connect Head Phone and other side to BB's Audio-
In slot ( which is at corner ).
I am giving below command after mounting SD card
arecord -t wav -c 2 -r 44100 -f S16_LE -v k
Then after some time I am pressing Ctrl+C.
Is there anything wrong?

My basic idea is just want create small application to play a wav file
or
small amount of predefined data from buffer on BB with kernel from
code.google.
Is it possible? it may be but as I am new to this world I need group
members help to do so.
Till now I could able run "hello world " program.
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
