This is a long-standing problem. While it is not intentional, sometimes
newcomers to jack on Linux tend to pull out the soundcard (USB) before
shutting down jack. This results in jack permanently hanging to the
point where one has to force-shutdown the machine. That is at least the
case on Ubuntu 14.04 (and was on 12.04) with lowlatency kernel. Trying
to do sudo killall -9 jackd makes no difference. Essentially, it is
impossible to destroy the process and reboot hangs because of it.
Any idea what can be done to minimize this problem or alleviate it
altogether?
a workaround is from a terminal type:
pidof jackd
you'll get a number such as 3772
then type
kill -9 3772
May need to be:
killall -9 jackdbus
Generally, when someone asks they get told:
killall -9 jackd jackdbus
:)
But by default Qjackctl as it comes from ubuntu repos starts jackdbus, not
jackd.
