Sigh... here goes... Jarod - it seems that for some reason people are
not getting what's going on here...

What Jarod, Isaac, and everyone else that has "been there" is trying to
say is the following:

1. OSS kernel drivers don't have to be on your box.  ALSA is what's in
the kernel these days, and it has an OSS compatibility layer for
programs that still want to use OSS.  That doesn't mean that OSS is in
your kernel.

2. Myth can use ALSA and it can use OSS.  It doesn't care whether it's
"true" OSS (such as the deprecated kernel drivers or those found at
www.opensound.com) or "emulated" OSS via the ALSA compatibility layer.

3. Leaving ALSA as installed will give you the OSS compatibility layer
PROVIDED BY ALSA.  Myth is fine with it (as stated in Note #1)

4. DO NOT USE "--disable-audio-oss" when building Myth UNLESS YOU FALL
INTO A PARTICULAR SET OF CIRCUMSTANCES such as building for OSX.  EVEN
IF YOU PLAN ON USING JUST ALSA!

5. Read Note #4 again
