I have asked the question in gentoo forum , but
it seems that very few people like hanging around
in forums , I didn't get useful method.
My sound card can't work normally , when I use music
player there is no sound .
Someone said that I need low-level codec support , I'm not
sure whether it is. Here is the information in sysfs, I really
hope you can know where the problem is.
# ls /sys/class/sound
audio card0 card1 controlC0 controlC1
dsp hwC0D0 hwC1D0 mixer mixer1
pcmC0D0c pcmC0D0p pcmC1D3p
seq sequencer sequencer2 timer
# ls -l /sys/class/sound/card0
