Recorded session ended up with no audio

[yigael]

Hello!
I am running into a 2020 type of situation with a recording. I set up OBS to record audio and video from a dj party. I got everything set as I usually do, add video source, audio source.
The audio source had signal as I was able to monitor it in the signal panel in OBS and I verified it by connecting headphones to the laptop. I left it running as it has been my regular process with other recordings and had no problem.
The next day Im about to check the recording and to my surprise, no audio is played, only video. Attached are the settings from OBS, and I really cant see what went wrong.
I dont know if there is some kind of tool to check the audio on MKV files, because I will be very sad if I cant get the 9 hour long set

Help!!

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

You may have set a different audio track in your advanced audio properties in the mixer.
