[Jack-Devel] [LAU] jackd terminates on its own

[Kjetil Matheussen]

(Just forwarding the reply to list now. Sorry if there's html in this mail,
it seems
like gnome terminal has started to copy fonts/colors/as well when copying
to the clipboard
(why?). Hope this doesn't manifest itself as html in the email.)

I removed the -T switch.

The current calling is:

/usr/bin/jackd -v --sync -P80 -ndefault -dalsa -dhw:M1010LT -r44100
-p256 -n8

The behaviour without the -T switch has indeed changed although the
problem remains as described.  At one point in loading projects Bitwig
will not be able to enable audio.  Here's the change in behaviour.

These few lines from jackd were taken when Bitwig cannot enable audio.

It loops endlessly with the last two lines during which time the
audio is not enabled in the newly loaded Bitwig project.  The
loop frequency is slow, perhaps each 5 seconds.

Curiously, after closing Bitwig jackd will continue looping with
the last line below.

Jack: JackDriver::ClientNotify ref = 2 driver = sys
