This next line looks like the modem driver.

And the modem is showning up as a sound card. How strange!

Good question. What is in your modprobe.conf file? Is the modem driver
loaded there, or is it somehow part of the hotplug stuff?

You might by hand try an 

rmmod snd_intel8x0m

and then a restart of Alsa to see what happens

/etc/rc.d/init.d/alsasound restart

No promises at all that this will help though.

If you're not going to use the modem then it wouldn't hurt to not load
it and save resources, especially if it's conflicting somehow.
