Hi Arun,
Thanks for the update! Finally i was able to play a wav file without much problems. But i came across few difficulties. Most probably it is due to the way i built the alsa-libs and alsa-utils. Earlier when i tried to play a sample wav file this was the result.
[root@osk5912 /]# aplay openal-1.wav ALSA lib dlmisc.c:118:(snd_dlsym_verify) unable to verify version for symbol _snd_pcm_empty_open ALSA lib pcm.c:2148:(snd_pcm_open_conf) symbol _snd_pcm_empty_open is not defined inside [builtin] aplay: main:583: audio open error: No such device or address [root@osk5912 /]#
Then I figured out we need to set the device when playing.
[root@osk5912 /]# aplay -D hw:0,0 openal-1.wav Playing WAVE 'openal-1.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo (it plays)
I tried encoding a wav file from a mp3 file and played using aplay
[root@osk5912 /]# aplay -D hw:0,0 rock.wav Playing WAVE 'rock.wav' : Signed 32 bit Little Endian, Rate 44100 Hz, Stereo aplay: set_params:954: Sample format non available [root@osk5912 /]#
This file is 32bit and the previous one is 16. I reencoded the wav file using the gstreamer to change the depth to 16bit
[root@osk5912 /]# aplay -D hw:0,0 rock2.wav Playing WAVE 'rock2.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo (it plays file even though reencoding was not proper)
Then i tried sample files found in alsa-lib.
[root@osk5912 /]# aplay -D hw:0,0 Side_Left.wav Playing WAVE 'Side_Left.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono aplay: set_params:959: Channels count non available [root@osk5912 /]#
So it cannot play MONO and 32 bit files ?? Any ideas how to fix this are welcome !!!!

Not yet. Would please share what you have done to make it work ? Also when I tried to strace aplay , it keeps looking for a </share/alsa/cards/tlv320aic23.conf> file which is not there in the alsa-lib package. Any idea what goes in that file ?
CCing in l-o mailing list too.
I dont know about that file. I didnt face that issue.
This is what i did to make it working. I guess its some omap1 related issue. This makes the omap_mcbsp_request(0) at boot time, instead of runtime.

I got it working. I2C_BOARD_INFO macro was wrongly intialized. Instead of tlv320aic23 i had written tlvaic23. Thanks to Arun for pointing this error
Can you hear audio playing? Because i had done some hack to make it working in 5912osk. I want to know you are not facing it or not.

Yes, it is there. but it shows as "tlv320aic23b" instead of "tlv320aic" Will that be the reason ????
