Hello,
I am trying to get a usb audio compatible sound card to work on the kwikbyte
kb9202 (www.kwikbyte.com) development board. It is a board based on the
at91rm9200 circuit which has an arm920t core. I am running kernel 2.6.13 and
I have the alsa usb audio device drivers compiled into the kernel.
The usb audio card is detected at start up and everything looks ok in the
"/proc/asound". If I do "cat /proc/asound/cards" the following is displayed:
-------------
0 [default ]: USB-Audio - C-Media USB Headphone Set
C-Media USB Headphone Set at usb-at91rm9200-1, full
speed
-------------
But I have nothing in the dev folder. No dsp, no snd, no nothing. So I have
tried with:
"mknod /dev/dsp0 c 14 3"
"mknod /dev/mixer0 c 14 0"
And then to get something out of the sound card:
"cat /dev/urandom > /dev/dsp0"
But nothing.
Are there anyone that has knowledge about this? All feedback is extremely
appreciated.
Best,
Jonas Norberg
ALSA will create dev nodes in /dev/snd
You will need udevd to be running for this to work.
Can you use ALSA as modules, so that the ALSA module loads after udevd
is running?
You would then need alsa-lib so that ALSA apps work.
You might also need snd-pcm-oss if you still need OSS emulation to work.
