soundcard - Won't recognize external sound card after latest update

I'm running Ubuntu 10.04.

Until yesterday, my Audiophile sound card was working beautifully. I ran the latest update, and now it doesn't show up under Sound Preferences. (When I plugged in a USB headset, that appeared under Sound Preferences and worked just fine.)

The sound card IS listed under aplay -l.

The sound card IS listed under lspci | grep -i audio, as Envy24 (I'm not sure why it's called Envy24 here instead of Audiophile, but that's always been the case.)

00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)

Here's the Alsa information: view

The sound card is listed as:

!!Soundcards recognised by ALSA

0 [Audiophile192  ]: ICE1724 - M Audio Audiophile192   
                     M Audio Audiophile192 at 0xdf00, irq 2

If I run Alsamixer from the terminal, the correct Audiophile sound card is the one shown.

I'm not sure what to do next. Thanks very much for any help/suggestions.

Hooray! I updated to 10.10, and the sound card works beautifully now.
