[linux-audio-user] Weird JACK behaviour w/ Qjackctl

[Christoph Eckert]

Hi,

when starting JACK from the command line on an USB Card 
Terratec Aureon 5.1 USB using

/usr/bin/jackd -v -R -p64 -dalsa -dhw:3 -r48000 -p512 -n4 -P 
-o2

everything works well.

But as soon as I use Qjackctl to control JACK with the same 
parameters then I get notches every 3 to 7 seconds.

I'm running

jackd version 0.99.0 tmpdir /dev/shm protocol 13
ALSA Driver Version 1.0.6
Linux vanilla 2.6.10 with the RT-LSM-patch applied.


Anyone got a similar problem?



 Thanks & best regards
