Question / Help OBS Linux Global Audio Offset

Hey there,

Really my question is quite simple, but I figured I'd give a little background about how I'm using OBS first:

I use OBS to broadcast jam sessions from my studio, and I recently purchased a Magewell XI100DUSB-HDMI capture card so that I can steam with my Canon Camcorder. My audio setup is complicated, but I have a number of MOTU AVB interfaces with mics all around the room. I'm creating two separate AUX mixes, one for drums and one for everything else. I have these AUX mixes sent from my analog mixing board over to another analog mixer near my drum kit so I can adjust the mix while we're playing. The drum-side mixer is just a Behringer USB audio class compliant mixer. I use two computers in this setup, one is a Hackintosh that I use for multitrack recording and the other is a laptop running Ubuntu that I use for streaming. I hook the magewell and the behringer mixer up to the stream computer to stream audio / video to Twitch and record multitrack audio from every mic on the Hackintosh in case I want to pull something out later and give it a more refined / processed mix.

This has been my process for a while now and it worked fine using the built in laptop webcam. My issue now is that the Magewell interface has significant processing time involved and the audio is coming into the stream before the video. I need to offset the audio to match the video so I guess:

TL;DR: Does the "global audio offset" setting exist in the Mac and Linux versions of OBS, or just the Windows version?

I can easily run Windows on my streaming computer if I need to, I'd really just rather not if I don't have to.

Not Global Audio Offset but you can adjust the offset for all sources individually now.

Just click the cogwheel where it says Mixer or Edit > Advanced Audio Properties

Note that you might have to change the Audio Buffering Time (Settings > Advanced) when you need higher negative value offsets.

Might also be better to ask in the OBS MP Support forum; this one is for the Classic windows-only codebase. :)

Thanks guys! I'll try that advanced audio properties window tonight, and if I keep having trouble I'll try the MP support forum or give up and boot my windows partition ;-)
