Alarm sound is only played once, Mac Vintel 1.2.3

[Timmeey]

I just installed Vintel on my new Mac.

after installing pyglet 1.3.2 AND messing around with the Chatlogs path, I got Vintel to start and work properly. but upon testing the sound (by Sound Setup -> Testsound as well as faking a intel report in game) I can only get it to play a sound ONCE, and then I have to restart Vintel.
Feels like something breaks upon playing a sound once.

I'm on Mojave
Vintel 1.2.3
Pyglet 1.3.2

Full logs while testing the sound via 'Sound Setup -> TestSound'

UPDATE:
If I keep spamming the Testsound Button, it keeps playing the alarm sound, but if I wait a few seconds after the last alarm finished, I cannot get it to play another alarm. This reenforces my idea, that something in the sound system gets stuck, once it plays a sound and then closes/pauses the Soundsystem if there is no other sound played after a few seconds"
