I wouldn't doubt that as SB was initially pretty reluctant to work with
the open source developers.

But that card was a nightmare load on the system - 5 IRQs and 2 DMA channels
consumed, as I recall.  It has wreaked havoc on many a system.

Any card with hardware mixing is a great thing.

Yes, but I've not done more than run a few things at the same time, and none
front/rear - I only have a 2.1 system.  However, if you use KDE and ARTS, 
it'll interfere.  Linux is not as clean as WinXX nor IRIX in regards to sound.
They are getting there.  While ALSA with dmix will allow the mixing, you'll need
to spend time setting it up.  It might be more benefical for you to combine ALSA 
with JACK - 

[ I] media-sound/jack-audio-connection-kit (0.99.0-r1):  A low-latency audio server

But not every application works with JACK.  So there are some helpers, but it
still doesn't cover everything.

If you have esearch just do an - esearch -Sc jack
