Ralf helped me a bit further off-list. It seems I needed to modprobe snd-hrtimer Now oom pretty much freezes as well when I tell it to use that, qtractor doesn't complain, at least not immediately, couldn't try further yet. Kernel is 2.6.31.4-rt14 Haven't tried this yet since I'm not sure it makes sense: chgrp audio /dev/hpet So even when hpet is available, hrtimer is the one to use? _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo/linux-audio-dev
