[mythtv-users] Trouble with Sound Blaster Live 24 bit.

Has anyone managed to get the Sound Blaster Live 24 bit (ca-0106) card working?
I'm trying to set it up on a fresh FC3 install with atrpms after
screwing up alsa on a previous install trying to get the damn thing
up.
I've followed Jarod's directions and the steps at alsa.opensrc.org and
everything appears to be in place. I'm running alsa 1.08 and the right
driver for the card, ca0106, is loaded. I've adjusted the
modprobe.conf and .asoundrc files according to the directions from the
alsa site.
The system is a P3 733, 512 RAM, PVR-250, nvidia g2. The sound
previoulsly ran through the on-board VIA 82xx, which worked but with
low levels.
I've set levels in alsamixer and Kmix, which both show the CA0106 card
having all allowable levels set at around 70. I've disabled arts.
System Settings -> Soundcard Detection finds Creative Labs SB Audigy
LS and the snd-ca0106 module and has it set as primary device, but no
test sound plays.
Everything I see indicates the card is working, but I can't get any
sound out to a pair of standard PC speakers. I know that they work,
and I know the card works properly in XP Home.
Some relevant output:

I know that this card has been a problem and I probably wouldn't be
spending time on it, but it worked when I first installed it. I was
also putting in an ATA controller at the same time, and pretty much
skipped over configuring the soundcard when it worked right away.
I don't think I changed anything with the ATA, but after loading it
and unloading it and a few reboots, the sound didn't work anymore, and
I've been completely unable to get it back.
Any ideas? Will this card run or should I exchange it?
