I observed this issue before and it came back now.
I create a layer and made a simple sequencing.
So, it is just running in a loop and out of the blue the audio stops and starts after a few seconds again.
Sometimes it does it - sometimes it doesn’t.
Now I have also linked it via network to my Ableton live, so not the internal sequencer is playing, but Ableton playing midi tracks to the Zynthian midi channel and the same thing happens.
I know if I will reboot, the issue might not be there again, but at some point, it will show up again.
I observed this some weeks ago for the first time, die updates in between and today it is doing it again.
I have a very basic setup with a Pi4 8GB and an external audio card connected the NI Traktor Audio 2 MKII which works just fine.
I can’t figure out what causes these dropouts.
