Ok, so, I run qjackctl as root with realtime priority and...
it works (or seems to). However...no applications that use sound can run -
for example xine returns "could not initialize audio driver." Realplay
refuses to start. Audacity (and most other audio apps) says "No soundcard
configured" and so on.
So....what's the next part? The Jack FAQ page suggests that the problem is
that the Jack server is running as root and the apps are not, but I can't buy
that this is the problem if Jack will only run as root, since that's a huge
BTW - several people asked about kernel version - I'm running 2.6.5-7 on SuSE
9.1 (default kernel upgrade).
Thanks much for the help so far :-)
