This issue occurs when trying to send too many DMX messages at the same time stamp. Audio output from audio Tracks pauses for a fraction of a second before the message is sent and playback continues.
If there is audio output from Layers happening at the same time as audio output from Tracks when the messages are sent, the audio output pauses with a burst of noise before continuing.
Just going by the anecdotal evidence based on the DMX I’ve got in my current project, 6 messages at once causes glitches but 3 does not.
I first noticed this issue in 1.3.18, still present in 1.3.19. It was NOT present in 1.2.5 - currently trying to downgrade to confirm.
I’m using an ENTEC Open DMX USB interface on Windows 11.
