[LAU] jack2 + arch trouble

[Atte André Jensen]

Hi

I had some problems with my jack recently, and today something new 
happened, that I'm actually able to reproduce:

In ardour2 "export range markers to multiple audiofiles", *but press 
cancel before it's finished*. I tried various settings, for instance 
both wav/flac and 44.100/48.000 (my jack sample rate).

After this ardour still plays at more-than-normal-speed (no sound is 
heard), like it's still rendering, although the dialog disappears. I can 
force ardour stop playback py pressing the close button of the window, 
but it only stopps rolling, after a while a "this window might be busy 
and is not responding" dialog is shown, cliking "yes" (I'd like to force 
quit it) will exit ardour.

Now to the actual strangeness: At this point jackd is screwed, I cannot 
start clients, it seems like jackd is not running to them. qjackctl 
looks ok, but if I switch to another workspace and back it's gui is all 
grey and I cannot exit it, except with the killall command. Top shows 
jackd is still running, but I can't killall it, even logging out of my 
xfce session and back in leaves it running. So I need to reboot to use 
jack again.

I'm 99% sure it's not ardour, since this also happened with other 
clients, although not at consistent and I haven't been able to reproduce 
it before.

Some info:

atte at blokhus:~$ cat ~/.jackdrc
/usr/bin/jackd -v -P85 -t2000 -dfirewire -r48000 -p256 -n2

atte at blokhus:~$ jackd --version

atte at blokhus:~$ ardour2 --version

I'm running over my edirol fa66 firewire soundcard. I'm running arch 
linux on a thinkpad X61s, and I'm pretty sure the system was running 
fine about a month ago...

Any ideas or suggestions would be highly appreciated :-)
