Since qjackctl has the wrapper script to suspend Pulse Audio I shied away from it, although I realize that I could have called the binary directly and skipped the script. However, I did it from the command line. Firstly, I checked the jack version [1], which appears to be correct as it is jack2 and in Natty. My first test was to start playing an .ogg file with Totem and then try to start jack from the command line. The result was that jack found the hardware locked...Ptui!

When I ctl-c to stop jack then Totem started up directly and began to play the song. At this point I didn't try either 'pacmd' lines until I hear back from you as it seems you expected this to work. I realize, however, that there is a real chance that I'm doing something wrong too :) ScottL [1] <a href="http://paste.ubuntu.com/608805/">http://paste.ubuntu.com/608805/</a>
