[LAU] qjackctl does not reflect state of jackd

[Eric Steinberg]

Hi Nick,

I can confirm that Rotter stops recording after the jack server receives
three or more xruns.  The program seems to be running, as does the jack
server, but all files are instead about 1k in size and have no audio.  Any
ideas?  Thanks!
