Neither "sudo kill -9 <PIDs of jackd, qjackctl and qjackctl.bin>" nor
"sudo pkill -9 qjackctl"
nor closing the terminal in which qjackctl was executed eliminates
this problem.
Since this was a clean install with very little added beyond ambdec,
tetraproc and mhwaveedit,
I don't have any explanation for this problem except bad karma between
the current UbuntuStudio
and qjackctl. On one occasion when starting the reboot, I got an error
message asking if I
wanted to wait for process Unknown to complete.
The good side to this is that UbuntuStudio 10.4 boots up quickly.
Does anyone have any ideas?
Thanks,
John
What output do you get when doing: lsof | grep snd
