[alsa-devel] Unable to play aplay
Hi ,
I want to play and record audio file in my custom atmel 9263 board running with linux(2.6.20). when I tried to play aplay for a wave file, I got
$aplay /home/alarm.wav ALSA lib pcm.c:1707:(snd_pcm_open_noupdate) Unknown PCM default aplay: main:446: audio open error: No such file or directory
$aplay -l aplay: device_list:187: no soundcards found...
$cat /proc/asound/devices 2: : timer 3: : sequencer 4: [ 0- 0]: digital audio playback 5: [ 0] : control
Can you tel me where I am doing wrong..??
Thanks in advance..
Vasudha,
Could you please check the device nodes in /dev/snd folder? The desired output is:
[root@ /home]# ls -l /dev/snd/ crw-rw---- 1 root root 116, 5 Jan 1 00:00 controlC0 crw-rw---- 1 root root 116, 4 Jan 1 00:00 pcmC0D0c crw-rw---- 1 root root 116, 3 Jan 1 00:00 pcmC0D0p
If the nodes are not there, you have to create them first before trying aplay.
Regards, Anuj

I inserted modules to my linux kernel (2.6.20)like..
$insmod snd.ko $insmod snd-timer.ko $insmod snd-page-alloc.ko $insmod snd-pcm.ko $insmod ac97_bus.ko $insmod snd-ac97-codec.ko $insmod snd-at91-ac97.ko
After this, I am getting,
$aplay
No error messages..
