I only tested on one device (Intel/nVidia onboard sound), so I can't

No problem. Any chance you'll make a new release soon?
My main concern is to get OpenAL-Soft out to the distributions. I think
we're mainly waiting on the new Creative web site for this, though.

This might be useful (I've run into that problem here, albeit rarely).
I'm a bit surprised that it didn't just work through dmix, though (maybe
I don't understand dmix well enough).
