This sounds like quite a fancy card, but I really don't particularly need
fantastic sound functionality, and it doesn't seem to me like I'm asking for
that much. I haven't tried, but I'd be very surprised if 'doze couldn't play
a beep over an MP3 player with just about any sound card. Of course I know
shag all about sound programming and Linux' sound support has always been
behind the curve, so I suppose it's 'hard' in some way or other.
