Hy..

I'm working on a AT91SAM9263-EK.
I've compiled kernel 2.6.20.4 (with the patch founded in this site), and I also add AC97 usyng AT91RM9200's patch.

All goes Ok, except the audio.
A simple test (like "cat /dev/urandom > /dev/audio") doesn't make any noise out of the speaker, so it doesn't work.
When I try to use alsa to cofigure the board, configuration programs tell me that "No soundboard is detected"-

All seems to be ok, but the audio doesn'work.

--------------------------------

Here some information about the board configuration:

-I've start with an empty file system: I add the minimal structure to start linux (). I also add all the alsa devices.

-During startup audio is detected


-In /proc/devices appear audio and alsa devices:

- /proc/asound exists and has information about the board.

Have you unmuted the alsa controller with amixer utility ?

Or amixer does not work ?

Command line :

/bin/amixer set 'Master' 70 unmute
/bin/amixer set 'Master Mono' 70 unmute
/bin/amixer set 'Headphone' 70 unmute
/bin/amixer set 'PCM' 70 unmute

To create devices for alsa.

mknod snd/controlC0 c 116 0
mknod snd/hwC0D0 c 116 4
mknod snd/pcmC0D0p c 116 16
mknod snd/seq 116 1
mknod snd/seq c 116 1
mknod snd/timer c 116 33

Thanks, but still not work.

As far as devices concerned, I've used "snddevices" script to create the devices I need.

When I try to use amixer, I've got this message:

Have you the /etc/asound.conf file ?

#cat asound.conf
pcm.!default { type hw card 0 } ctl.!default { type hw card 0 }
