Question / Help Multiple Audio Tracks Not Working?

capturing to multiple audio tracks doesn't work. I setup the audio tracks correctly in the mixer. I have two mics and sound flower capturing the system audio. I set all inputs to track 1, and 1 channel for each input (mic 1 -> 2, mic 2-> 3 and desktop ->4). When I open the captured video in VLC or other programs that support multiple audio tracks, only track one exists.

Am I doing something wrong?

I routinely capture multiple audio tracks. They work.

Some containers do not support multiple audio tracks, like .flv.

I'm also not sure what you mean by "set all inputs to track 1". In the one audio track you have, which input are you getting?

I had the same issue after reconfiguring obs in 0.14.2 (with my previously used preferences). But after replacing the whole configuration folder with the old config folder, it works perfect.

You have to actually select which tracks go into the recording, just setting up the advanced audio properties isn't enough.

Sorry for the late reply. Didn't have e-mail notifications setup, apparently. Thought my question had gone ignored. Anyways...

This is the windows version (on a different computer at the time), but these are the settings I have setup. I'm saving to mp4 whith h264 encoder. That should support multiple audio tracks.

The one audio track a get is whatever is in track 1, so in this case, I'm getting all audio mixed in track 1. If I change it so that only desktop audio is in track 1, then I only get Desktop audio in the final video.

I thought I was doing this in the screenshots above. Is that not correct? If not, what do I need to do differently? I assume they are all added to the video because when I set it up this way, all audio I want to capture is in Track 1. I just can't separate the audio into separate tracks. Grouped together in track appears to be the only option I have.

Because you've probably only got track 1 set to record in Settings> Output > Recording.

That screen is missing from your screenshots above.

You're almost there. You've actually your mic going to tracks 1 and 2 and Desktop Audio going to tracks 1 and 3. So Track 1 should have everything if in the recording tab, Track 1 is set to record. If it is set to track 2, you'd get only the mic, and if track 3 you'd get only desktop audio. The .flv recording format only records one track, while mkv and mp4 support multiple, so you could just turn them all on and sort it out in the editor, if you so chose.

Streaming only supports one track, so you have to put all your devices on it, but you can send audio sources to more than one track, so you can simultaneously stream one audio track with all your sources, but then record three additional separate tracks with various audio sources so that you can change audio levels in an editor if you wish.

Doh. I never bothered changing to 'advanced' in the output settings. Thanks for everyone's help. I feel silly now.
