JACK latency change causes crash #35

Closed Holzhaus closed 3 years ago

Holzhaus commented 3 years ago

Reported by: p-yorick Date: 2008-02-13T10:44:56Z Status: Fix Released Importance: High Launchpad Issue: lp191518

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. :)

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? ;)

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

This still occurs in beta3 btw.

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.
