Hi,
I want to debug my audio since I had to patch the kernel from moblin
with a driver from Cirrus (cs4207).
The patch that I had was for the kernel 2.6.27 and since moblin is now
at 2.6.29 I had to update the patch so that it could work.
(I've attached the modified patch)
These are the steps that I've done until now:
- Download the kernel source from moblin
- add the patch from Cirrus
- recompile the kernel
now when I boot I see that another audio device is found. This is how
I see it:
[r...@localhost ~]# ls /dev/snd/
controlC0 hwC0D0 pcmC0D0c pcmC0D0p pcmC0D1c pcmC0D1p seq timer
[r...@localhost ~]#
[r...@localhost ~]# aplay -l

and this is the output fro aplay -L;

I have noticed that my pulseaudio is not running so I cannot use this
for playing a wav file.
How can I test my audio on my board? When I was using the original
kernel I was able to play audio with this command:
aplay -D plughw:0,0 <wavefile>
[r...@localhost ~]# ls /dev/snd/
controlC0 hwC0D0 pcmC0D0c pcmC0D0p seq timer
[r...@localhost ~]#
[root at localhost snd]# aplay -l

Any suggestions what else I can do?
