Yorick, does this happen in beta2 and/or SVN still?

Thanks! (I can't remember if I fixed this or not...)

This is still happening. Sp'ifically, it now happens on startup once
you've configured to JACK and closed down once - terminating JACK and
starting up again fixes it though (Mixxx realises there's no jackd and
reverts to ALSA I suppose).

I notice that the latency slider is now locked at 16ms for JACK
though. Is it actually 16ms or 0ms? But given the latency slider is
locked, I can't really tell if changing it on the fly causes a crash,
can I? ;)

Status in Mixxx: Triaged

Bug description:
When you change the latency with JACK selected as API, you get a fatal assert:

First time:
ASSERT: "m_pControlObject" in file src/controlobjectthread.cpp, line 32

Fourth time:
Debug: Opened PortAudio stream successfully... starting
Debug: PortAudio: Started stream successfully
Fatal: ASSERT: "m_pControlObject" in file src/controlobjectthread.cpp, line 32
Aborted (core dumped)

Getting the program back into this condition, I couldn't do though. Yet another race probably... The wonders of threaded programming. :)

Ok, thanks for the update Yorick, I'll have to play around and try to reproduce this on my system....

This was marked as fixed.... But was it?

Yes, latency is no longer changeable with JACK as an API, because it's
determined by the JACK daemon anyways.
