Not much, Mike. I just set up a new computer, with my last box having
an analog cable between the CD drive and sound card, and went through
the ALSA adjustments I mentioned so I thought it might apply to your
problem. Still, the timing of the upgrade with the failure is

The OPC step involves reading the disk medium which doesn't seem related
to sending out a digital signal over the bus, and that could indeed have
broken between the last time you were aware it worked, and now, but how
common would that be?

My first suspicion would still be changes in ALSA with the new OS before
a sudden catastrophic failure of the digital output.
