Good point - IIRC it's also possible to compile the ALSA modules outside
the main kernel tree. One way or another though, the ALSA kernel modules
will be required to use ALSA ;-)

But not always better. My laptop - with i810 AC'97 sound - works
/massively/ better with ALSA. With OSS all sorts of weird issues used to
turn up - sound playing at double speed, as if the clock had been
accelerated but only for the app with the sound device open ; apps
writing to /dev/dsp hanging indefinitely, etc.
With OSS emulation under ALSA, it works great. Oddly, using native ALSA
is the worst of the lot, barely working at all.
