Question / Help Multiple Audio Tracks with a single video?

[Simes]

Click the cog next to the word "Mixer" on the OBS interface and make sure your audio sources are being applied to separate tracks.

Hi, I may have stumbled on a solution that may help anyone still struggling for a simple solution, even though it's been a year. I exported the file as mkv from obs and then used mkvtomp4 to turn it into an mp4 file. Then I renamed it to .m4v and voila, all audio tracks appeared automatically when I imported it.
The conversion program also supports converting to m4v directly.

Works on DaVinci Resolve 16 really well, and it's free!!

Disregard my previous post. It looks like the issue was with OBS Studio. I was trying to use Type: Custom Output instead of Standard. I did this originally due to another issue I've already resolved. For some reason, the Custom Output only allows 1 track (hence radio buttons), while the Standard Type allows multiple tracks.

Thank you so much, I just made a post about it and you fixed it!
You made my day so much better thanks!!
