May well be a mixer settings problem: the ALSA drivers mute all channels
and set volumes to zero initally. Also, 'No sound applications work'
isn't very clear, error messages, strange behaviour reports, please ;)

Yes, you must delete or comment out line 1. After a reboot the ad1848 module
hopefully is out of the way. (there are other ways to remove unwanted modules
of course). You can check with '/sbin/lsmod' which modules are loaded. Note:
snd-ad1848 is _another_ module which _may_ be needed by ALSA for you soundcard.

Yes :)

These lines are for OSS/Free compatibility and you do need them for most
applications. I'm now listening to XMMS with the OSS output plugin, while
using the ALSA drivers.

Yes. If you didn't get any error it seems the ALSA driver was loaded!
