Oh, i am familiar with OSS and their website.

In my own experience Jack/OSS isn't as desirable as jack/ALSA. I haven't
used OSS lately in Linux, last time i did, it wasn't a glitch free
experience... but i did have FreeBSD8.1 running with Jackd, semi recently.
it didn't perform nearly as well as under linux ( even with the BSD kernel
tuned up) I heavily use jackd in my studio on several machines. OSS is
mainly a Unix thing these days. Not so much Linux. People use it
occasionally when they need to hack something to work(usually a legacy app),
but beyond that, OSS lost out to ALSA along time ago. Not to many apps
written in Gnu/Linux for OSS these days...in particular not for OSS4 - it
won't ever be adopted.

I also did state that i "jumped the gun on saying it is dead" and pointed
out Unix - but it certainly will never become the defacto standard in Linux.
that's not going to change.

Of course, PA isn't a viable option for wine, getting good glitch-free sound
is important - something that PA can't provide. Pa doesn't provide good
sound in VMware either. I actually just removed PA from Gnome3 today (which
just came through as an update in Archlinux).  I had to do it for the same
reasons you mention above - I use wineASIO with Jack, and also FST too.  i
despise PA and have to remove it on any fresh install of Linux.

happy times.
