After upgrading to Ubuntu Hardy (8.04), I'm having (too many) xruns on
two different machines. Both worked perfectly on 7.04.
On both machines the "RT" indicator on qjackctl keeps blinking. On 7.04
it was always dimmed, and everything worked fine. Does someone know what
that "RT" indicator in qjackctl means? When it is dimmed, do you not
have proper realtime scheduling?
On my laptop, with a Behringer UCA202 USB soundcard, there are xruns on
some of the "RT" blinks. On my PC, with an M-Audio Delta66, there are
one xrun on the first blink, and on every subsequent blink a message
saying "XRUN callback (40 skipped).". Then there's about forty lines
saying "delay of 36196.000 usecs exceeds estimated spare time of
11579.000; restart ...". I've included a portion of the jackd output below.
Things I've tried so far are modifying /etc/security/limits.conf,
installing linux-rt kernel and adding "nohz=off" in /boot/grub/menu.lst.
I've also tweaked the settings in qjackctl. Higher latency makes less of
the problems, but there are still xruns while the computer(s) are idle.
Any suggestions would be welcome!
