Convincing nForce3 built-in sound card to playback audio
I have an old AMD64 Shuttle FN85, which has a sound card built into the motherboard. Almost every time I reinstall Linux on this machine I have trouble getting the audio working again.
Turns out that un-muting the PCM and Master channels isn’t enough, you must also un-mute the Centre, LFE and Surround channels.
