Yeah... I'm new to linux audio world but this thing with jack and pulseaudio is really confusing. at least with kde wm you have an option to switch off pulseaudio.
The semi-solution is to force pulseaudio to go through jack, that is possible but it is reported to be buggie. There is this guy who made a ubuntu based distro that managed to make this work (from his site [http://kxstudio.sourceforge.net/]): > For Audio, users will love to know that Jack2 in present and that *all* > audio output is send to Jack. This includes Pulse-Audio, which means that > you don't have to stop Jack if you need to, for example, open a Web Browser > to watch some tutorial videos. > http://kxstudio.sourceforge.net/index.php?option=com_content&view=article&id=44&Itemid=12 BUT: Known issues PulseAudio will randomly crash when ran on a real-ttime kernel. KXStudio users can install the "kxstudio-kernel-lowlatency" meta-package for the kernel v2.6.32 with preempt+lowlatency config; Then when the computer [re]boots, hold Shift key after the BIOS splash, but before GRUB loads. PulseAudio will crash when Jack is stopped, which is kind of expected anyway. :) 2010/7/13 Ralf Jung <[email protected]>: > Hi, > > I'm very interested in how you get pulseaudio and jack working.
