Er, I have a feeling it wasn't actually, on second thoughts. The quality was
better than in DOS. Maybe it was failing to use the Allegro mixer at all...

No. :-) However, the digital volume bug may be linked with the quality bug.
I'm not sure. Can anyone investigate?

Note that the quality will only make a difference on 16-bit drivers.

Which raises the question, why doesn't it work? :-(

I'm about to travel, meaning I won't have access to any e-mails already
sent. Can I leave this in your capable hands? :-) Of course I can still
reply to e-mails sent from now on...
