Bug Report Can't record multiple audio tracks on Linux

[Fabian]

I uninstalled obs-studio, obs-plugins and libobs0, used the modified cmake command and now it worked and even saved my settings!
But sadly I still can't record two tracks. Log is attached.

 

[Osiris]

That log shows 2 tracks being recorded.

 

[pkv]

as Osiris said, you need first to uninstall the earlier package you installed (the one which was version 0.15): sudo apt-get remove obs-studio
As to the rest of the commands, they work fine now

 

[Fabian]

@pkv I did that and the installation worked, it shows the higher version number now.
@Osiris Here is a log file and the corresponding recording. There is no microphone track.
Since the forum doesn't allow me that file size (but also doesn't tell me which file size is allowed), it's on Google Drive: https://drive.google.com/open?id=1jzn_07HcUNHU55hlMXvfhwSQZeIuUGJc

 

[Osiris]

That video has 2 tracks.

 

[pkv]

the log does show two tracks recorded; post a screenshot of your Advanced Audio Properties and also of settings > audio

 

[pkv]

osiris beat me to it; but i do hear audio on the two tracks in the recording ...

 

[Fabian]

Then one of them is empty, because neither VLC, nor OpenShot, Shotcut (two video editing programs) or Telegram messenger play any microphone audio, as well as Google Drive or YouTube when uploaded.

 

[Fabian]

You hear me saying "Test" and everything? How is that possible? I don't hear anything!

 

[pkv]

there is audio in the two tracks ; in the first track (desktop audio) audio starts at about 21 sec; in the second track, i hear the static from the mike and then "test" at about 13 sec ... You must be tired

 

[Fabian]

Whaaat? Is it April fool's day? I have now tried it on my phone, Google Drive, MX player and Google Photos all play no microphone audio.

 

[Fabian]

Now I found it! It's switchable, not parallel!
Ok, now I urgently need to know: Did the 0.15 version also support this? Because if yes, I have recently thrown away 27 hours of audio, thinking it was unsavable.

to check your video, use vlc; Audio menu allows you to select the track.
You seem to misunderstand what is an audio track and an audio channel. A mkv/mp4 can have one or several tracks. The tracks themselves can be mono, stereo or more; for instance 7.1 . If you want to mix the mike and desktop audio, you should put them on the same track. If you want them to be on separate channels, you'll have do some panning ==> the simplest to do that on linux is to process your audio in a daw and route it to obs with jack. On windows, you can use the rematrix plugin (on linux you would have to compile it).
As to obs 0.15, can't say; never used it.
Case closed as far as i'm concerned. Won't monitor the thread any more since there is NO bug.
