All sound devices are handled by alsa. It's bad that alsa doesn't have
a good GUI configuration because I believe it can pretty much replace
a sound server nowadays. But what you say to some extend is done *by
default* by alsa already.

I'm trying to understand if the crashes are seen with pure alsa as
well. If not then configuring for alsa can make current pulse users be
able to use SD much more conveniently. As well will identify to some
extend the culprit of the crashes. Personally I'd like to know the
best reliability of SD that can be achieved so I decide whether there
is a chance to make it work for my wife. I certainly will not ask her
to restart it few times an hour (and she would not accept if I did).

Actually yesterday I made Bulgarian working with SD and orca and I
found it working fine. But I used it only for 10 minutes so I can't
say it is stable enough. Again I'd like to know it's reliability from
actual users before I jump in configuring a very complex system.
