Works for me on Ubuntu 8.10, but it doesn't work properly with hibernation. After waking up from hibernate, the sound is completely garbled and worthless. If anyone has tips on restarting the card after waking up I'd really appreciate.

Try rmmod for the kernel module of the driver before heibernate and modprobe after. That might be work around to make driver not to mess the state.

I have been using an M-Audio Revolution 7.1 for a couple years on my linux box,
and I use it as a Myth frontend/HD home theater. The card works great...

Audio input does not appear to be functional unfortunately.

I haven't tried fixing the hibernate issue, I've got too much hardware having trouble with hibernate. I just turn my computer off nowadays..

If you have a spare partition or USB stick, you may want to try OSS4.

this card works great under alsa for me

As this thread comes up quickly on Google, I'll post it here.

Using this card on Ubuntu, it sometimes randomly, for no reason whatsoever, becomes insanely loud in an instant, clipping beyond the edge of madness, ridiculously loud, deafening. If you're using head/earphones and have a weak hart, this sure can kill you.

Whenever this happens, there is only one thing you can do: reload alsa.

killall pulseaudio
sudo alsa reload

Or just reboot the computer, obviously. This problem occurs completely at random, there is nothing to be found in dmesg so I wouldn't know how to troubleshoot it.
