I have the following problem with the new snd_hda driver; the driver
attaches succesfully but I get no sound, and writing to the /dev/dsp*
nodes causes an error on dmesg:
pcm0:play:0:dsp0.0: play interrupt timeout, channel dead
When I try to "cat /dev/urandom > /dev/dsp0.0" I also get:
root at aphax-laptop:~/hdatemp# cat /dev/urandom > /dev/dsp0.0
cat: stdout: Invalid argument
(Same with all /dev/dsp* device. nodes)
I did get some noise/crackling the first time I loaded the driver and
tried to play a movie, but I can't seem to reproduce it anymore, even
after rebooting. I do consistently get this 'popping' noise when the
driver attaches though.
I've fiddled a bit with plugging-in/unplugging headphones and with the
volume and mute sound keys on my laptop, to no avail.
Anyway, without further ado, the requested info:
