Summary0004948: Playhead/playback issues when changing playback position
DescriptionSVN 12923:

I have a session created recently on beta4. While playback, clicking in the markers/ranges/tempo/meter area to change playhead position will stop the playback while the playhead will continue to run. Change the position again and it works. Do it again and it stops while the playhead continues, and so on...
Same thing happens when changing position using the 'p' hotkey.

Can't figure out how to reproduce it, new sessions seem to run fine. Console says nothing.

Just discovered that this happens only with Jack transport enabled.

Can we get a copy of the session file?

please try 1.9.8 or jack1. i am about 98.784% certain that this problem is caused by the version of JACK you have.

On 1.9.8 and SVN 13221 the bug is similar, except that instead of the audio muting when changing playhead position the only bus track in the project (a bus with Hydrogen input) will continue to sound but heavily distorted. Don't know if I can manage testing it with Jack1, last time I tried to migrate resulted in a catastrophy when so many programs depended on it...

(virtually) no programs depend on jack2 or jack1. unfortunately, several distros have set things up so that it is very hard to make the switch. however, for some reason i did think it might have been fixed in 1.9.8 so we can definitely eliminate that as a possible explanation.

i've seen a similar issue in latest git, which is caused by "auto-return" and grid enabled. when auto-return is enabled and a3 is jack transport master, moving the playhead by mouse and "p" will result in a rapidly looping playhead.

farbro, did you have grid and auto-return enabled?

paul, do you think this issue could be fixed easily? if not, auto-return and JACK transport should be mutually exclusive.

Don't know if I had auto-return enabled, but I can no longer reproduce this bug. But I can confirm your issue nettings, but only for fresh projects. I've loaded several older sessions created with the betas, and they do not go crazy with the playhead but instead simply refuse to change position.

By "grid enabled", you mean the snap option? I can't see that it matters for me.
