For AC97 there are "codecs" in the kernel config. A safe choice is to select them all. The output you gave is not very helpful or informative, but I'll ask just a few questions/suggestions: * Looks like maybe you have 2 sound cards. Are you going through the correct card for output? * Did you go into alsamixer to verify that the appropriate outputs are unmuted? * Try "aplay" or "speaker-test" or something else low-level to see if even basic output is working. It could be your sound card is fine but you don't have the correct support for whatever music player you are using.
[gentoo-user] Problem with sound card
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 lrwxrwxrwx 1 root root 0 Oct 25 03:37 card0 -> ../../devices/pci:00/:00:14.2/sound/card0 # ls /sys/class/sound/card0/ audio controlC0 device dsp hwC0D0 id mixer number pcmC0D0c pcmC0D0p power subsystem uevent Regards Lavender
