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 !!!!
