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. jordan -------------- next part -------------- An HTML attachment was scrubbed...
