5.2.1-RELEASE-p9 with pcm in kernel identifies onboard nForce2 card (K7
Triton GA-7N400-L mobo, enabled in BIOS), creates devices and behaves
correctly in every way except for producing any sound. No errors.

The /dev/{audio*,dsp*} devices appear to read sound data, but nothing
comes out of the jacks.

Searching the web and list archives has turned up nothing similar. All
ideas appreciated.
