 +A first try at using a pm-utils script. This script saves the priority state of all irq* processes and restores them after a resume. It only restores the priority for processes that still exist after the resume, and will do nothing for new processes (ie: you plugin a usb card while the computer is sleeping). That would be taken care by my previously posted udev script which would change priority of newly inserted soundcards. I put 05rtirq it in /etc/pm/sleep.d/ directory... it seems to be working fine in my laptop.

 +==== Tip: Pianoteq - software synth - on Linux ====
 +\\
 +(tip by: Edward Diehl, LAD, 2012-09-02)
 +\\
 +I wanted to mention that Pianoteq does provide a linux VST which does
 +work in Ardour and Qtractor.  However, the default version provides 5
 +output channels which Ardour does not seem to like (because it expects
 +stereo output).  However, if you append "_2chan" to the plugin library
 +name (e.g. Pianoteq.so to Pianoteq_2chan.so) , the plugin will output
 +only 2 channels and work happily in Ardour.
