[mythtv-users] asus pundit + alsa spdif flailing

[Paul Phillips]

Aargh.  I finally had my myth box running correctly with 5.1 sound and sat
my wife down to demo our new digital library of DVDs.

Except audio was gone.  I hadn't changed anything and it had been working
fine for a couple days, so I figured it'd be a quick tweak.

Eight hours of miserable effort later, I give up.  It's gone, inside or
outside of myth.  What happened? I feel like I could have written a sound
system from scratch more easily.  The pain is greatest because I don't
know why I was abandoned to this symphony of silence.

A look at /proc/asound/pcm does not list the digital device that I think
is supposed to be there, and light is no longer emitting from the optical
output, though that state of affairs may be a result of one of the many
things I've changed trying to get sound back.  I am out of ideas and have
turned desperate.  The myth "WAF" plummeted last night when the movie
evaporated, so the marriage of myth and marriage may depend on my
recovering audio in the near future.

All software is the latest debian unstable, kernel 2.6.5.  I have read
and tried pretty much everything ever written on the net regarding alsa,
spdif, and intel8x0, no matter how improbable or ill-conceived.  The
IEC958 settings are all enabled, etc.

I anticipate my next move involving a circular saw.
