Replying to my own post - an update:
I have three sets of partitions on my BE/FE's system disk for various
iterations of Myth.
After the upgrade above (JYA's 0.23-fixes/0.24-trunk-25171, with plugins
at 25221, on Ubuntu 9.10) - Myth was basically unusable. Sound was fully
b0rked and I couldn't access my videos (other than Myth recordings) or use
any plugins. I copied this setup to a second set of partitions and
restored my pre-update system from backup (so I now have a working system
again).
The interesting part: I booted again into the dysfunctional system and
did a dist-upgrade to 10.04.
After this upgrade: SOUND IS WORKING - in 5.1, seems reliably - WITHOUT
the need to fart around with alsamixer (as I've had to do for a long
time!), at least with the Myth recordings. ALSA:iec958 is the audio
device, and the "separate audio device" is hw0,1.
I still can't run ANY of the plugins (Protocol version mismatch: the
backend appears to be running 56 and the plugins, 57, or vice versa). It
appears that I won't be able to run my new install until the next update,
when the protocols match.
However, as JYA has been madly updating the sound code, I just wanted to
let him know that this problem may FINALLY be fixed on this machine, with
the changes he's made. Much appreciated!
Bob
