It appears that the Nvidia OSS driver doesn't decode anything for the
SPDIF.  It expects 48kHz data.  If it's not (like the 32kHz recordings I
have from Myth) it sounds like the Chipmunks.  Ogle passes the Dolby
Digital through; I've played a few DVDs this way since the new Nvidia
drivers came out, and my receiver displays that it's receiving the
appropriate kind of data.  And I played a test DVD, and it played
through the speaker it said it should be.
