Does anyone know if there has been a change in the ALSA code in recent 
kernel versions?

 the PVR output connected to the NForce line in, and I can hear sound 
on the _analog_ output, but not the digital.

Indeed, that's the key.  I ran this problem for 2 days solid trying to get
SPDIF to work, but it just seemed a complete loss.  There should be 3
'volume' levels on that particular mixer setting.  Setting it to the
various levels enables/disables different types of output from your
digital jack.  It should be the AC97-SPSA that you are looking at, and it
should be set to '0'.  I've also got the AC-Link option enabled on the
'playback source'.

Good Luck!

Cool
