OSS

Hi

(apologies if I replied already, I had a mild crash as I was hitting Send ;)

At this stage for compatibility I would imagine. There are a few drivers
that haven't been ported to ALSA yet.

Does it also show an ALSA one? In warty I see ALSA and OSS mixers (the
latter coming from the OSS emulation layer). In hoary I only see one or
the other because newer gnomes seem to have noticed that having the same
mixer twice under two names is a bit silly ;)

Usually that is because the hardware only supports one audio stream at a
time (ALSA's webpage has a chart that details which cards can mix multiple
streams in hardware). You will probably need to run something like 'esd'
as mentioned elsewhere on the thread. I'm not sure what the ALSA approach
to this is as I have a card which mixes in hardware, but I expect there
are others here who know.

Do they make sound even if nothing else is running? If it's the esd
situation described above, the first thing to try and make sounds will win
and everything subsequent will be silent.

Assuming your soundcard is supported by ALSA that would be the best way to
go imho.
