Video clip plays glitchy when I switch Audio Output Device

[TanyaGoehring]

Hi there,

I have a clip that has audio and video - it plays fine when the Audio Output Device is set to my laptop but as soon as I switch it to my projector, the clip plays too fast and is really glitchy. When I switch back to my laptop, the clip plays normally. None of master or clip speed settings change, though (that I can see).

I'm running Arena on a MacBook Pro (13.4.1) and sending out to two projectors.

I'm hoping to connect a speaker to each projector so that I can play the video and audio through it without having to use Ableton.

Any ideas?

Many thanks!
