omap osk audio

Dear all,

I am working on omap osk. i want to enable audio on it. But am not
able to do that. The kernel boot log says it has initialized audio
device. but i am not able to configure the audio setting nor run some
recording code. the system hangs and i have to restart.

the kernel boot code says:

TLV320AIC23 I2C version 1.8 (10-Feb-2006)
audio support initialized
ALSA device list:
#0: OSK AIC23

i have created nodes:

# mknod /dev/mixer c 14 0
# mknod /dev/dsp c 14 3

thanx,
Shareef

RE: omap osk audio

I see that the drivers getting loaded are the ALSA drivers. You are
trying to create the nodes which usually the OSS applications use to
talk to the OSS audio drivers. Unless you have the OSS emulation enabled
in the kernel/user space, you can't use the audio device through these
nodes. Use some ALSA application. Refer to ALSA website for creating
your own sample application. Also you will need to create the device
nodes for ALSA and also place the config files accordingly.

Please someone correct me if I am wrong.

Regards,
Suresh
