On a system where I can't use OSSv4 for sound (due to MIDI) and need to
fall back to ALSA, I've hit ALSA's insane latency issues and therefore
decided to use JACK. I'm trying to set-up a machine suitable for
music/audio production.
But JACK just stops working at random. Sometimes it works, but after a
a while it doesn't anymore. And when that happens (which happens sooner
rather than later,) restarting JACK (with qjackctl) doesn't help; only
rebooting the machine does, which as you can guess is very annoying.
I'm appending the error message in case someone can help me figure out
what's going on.
I'm on AMD64, kernel 2.6.35.1 (gentoo-sources-2.6.35-r1) using in-kernel
ALSA on a SoundBlaster Live 24-bit.
