I've done some more checking on this and I'm very puzzled. MythTV is
the only thing that is broken. I even completely removed all the HD3000
drivers, modules, etc. and rebooted (everything but physically yanking
the card). aplay (ALSA) works fine, as does bplay (OSS, /dev/pcm).
Mythfrontend doesn't make a peep, even playing recordings that worked
fine two days ago. My alsamixer settings all look fine, so I'm puzzled.
I'll try to get sound working and then try the different patches.

Interesting. Good tip, too, on the playback. Do you usually recommend
mplayer ofr testing?

I haven't seen any logged problems or other indications of trouble, but
I'll keep my eyes open.
