Question / Help Sync issues with OBS on Mac

Hello! I'm having an issue where two audio sources will go in and out of sync from each other during a stream. I'm running OBS 22.0.3 on Mac and the two audio sources are a USB input and desktop audio capture using iShowU Audio Capture. I've added a delay to align the two sources but, they end up going in and out of sync over time without me doing anything. Would love some assistance, thanks!

Open the Audio MIDI Setup app in the Applications/Utilities folder and check that you've got the same sample rate for all the devices you're using, and that they are set to the same rate that OBS uses, which in your case is 44.1 khz.

17:20:18.134: audio settings reset:
17:20:18.134: samples per sec: 44100
17:20:18.134: speakers: 2

If you have any devices that can't be set to 44.1 khz, you may need to change them all (and OBS) to be 48.0 khz.

This is one possible cause of a recording drifting out of sync over time.

Thank you for the reply! I think this is most likely the issue! Seems to be working now with everything at 44.1. We'll see how it goes over an extended period of time. I appreciate the help!
