Bug Report Video recorded SILENT with audio shown on audio-bars

Hi, I recorded a video with two audio tracks and both audios were silent!
The audio bars were showing data coming in though, just as usual.
The problem happened once and didn't repeat.
Was that a codec issue? Please help!

I'm using OBS 21.1.0 on Ubuntu Studio 16.04.
The audio was taken from ASIO device using Jack.

I attached the LOG file, the codec info from VLC of the recorded video and the Desktop screenshot (it's a Buddhist event).
Below are some un-usual lines from the LOG:
