Issue with the priority of the sound cards using rtirq - Linux-audio-user

1 May 2012

Hi :)

since I've got a strange issue with rtirq on US Precise only. Is there
anybody having a strange output for
        /etc/init.d/rtirq status
too? I remember that there was a post, when US Precise wasn't released.

Regards,
Ralf

 The reboot doesn't improve anything:(. 
So the output of /etc/init.d/rtirq status is the same as in the other 
mail? That's really weird. The only thing I can think of is that 
something else (another script?) is prioritizing stuff too (like the 
nvidia and ohci_hcd processes). The steps between the priorities 
strengthens my suspicion, it should be 5 but some processes do not get
a 
prio that can be divided by 5 (like nvidia which has prio 82). No one
on 
the Ubuntu Studio list encountered the same issue? Maybe Ubuntu (or 
Ubuntu Studio) prioritizes processes somewhere else.

Best,

Jeremy
