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.
