Question / Help Static on Youtube livestream, but no static on local recording

[jabiggers]

I've searched all over the forums and google for anyone having a similar issue and haven't found anything.

We have 3 video capture inputs and 1 audio capture input

Elgato HD60 Pro - Camera 1
Elgato HD60S - Camera 2
Cam Link - Presentation PC
Line in from Sound board

Monitoring the audio sounds fine, and recording locally sounds fine. It's just when streaming to YouTube there is a static over all audio. I have not tried other live streaming platforms, but I prefer YouTube because they support 1080p60fps

I'm attaching the log

Here is a link to a livestream:

You can only really hear the static when people are talking, not during music, because the music covers it up.

No one has had this issue before?

Found the issue finally. Audio was out of phase on Left and Right channels. Sounded fine on local recording because we had a stereo headset. Youtube downmixes the audio to mono which is why it had so much static. I used some software to get it back in phase and problem is solved.
