OBS soundtrack problem

[NoOby1912]

Hello guys,
In the attempt to record two soundtracks from one video i changed the advanced settings as shown in the picture, using trace one for the desktop and trace two for the microphone. Unfortunately my voice is not to be heard in the video (stupid as I am I recorded a 2h video without proper check before).
Is there any chance to find that audio, and if so, where and how?

Greetings :)

Probably effed. This is the default.

If there are multiple audio tracks in a video, keep in mind no media player will mix them and play all of them at the same time. You have to switch between them in the audio settings of the media player. So check if the media player shows multiple audio tracks and switch them.

The real use of multiple audio tracks is the ability to postprocess them separately and mix them with some postprocessing software and replace the multiple audio tracks with the mixed track.
