Summary0008114: Regular playback dropouts due to [ERROR]: JACK: Cannot callback the server in notification thread!
DescriptionOn my livestreams I use Ardour to play viewers submissions. It's usually a dozen WAV files in the session on a single track, playing one at a time.

However I regularly get audio dropouts. This is something that happens since I remember (I've been doing the streams for more than a year now, every month).

I've checked and Ardour spews a bunch of error messages every time it happens, and all of them look exactly the same:

[ERROR]: JACK: Cannot callback the server in notification thread!

I've tested in Zrythm, and it plays back fine, no dropouts, and no JACK errors.

I haven't yet tested with 6.0 just yet.

Can anybody reproduce this?
TagsNo tags attached.

(1) regular drop outs are the issue here, and may or may not be ardour related
(2) what version of JACK ?
(3) we're unlikely to pay this any attention unless it also happens in 6.0
