Audio streamed & recorded with continues mute/unmute slices

[Streamia.gr]

OBS audio settings:
- Sample rate: 48kHz
- Mic/Aux: USB audio CODEC

Windows audio devices:
- All input/output audio devices are set to sample rate 48kHz

The problem:
- Streaming started normally.
- Audio streamed and recorded with no problem.
- At some point I started to stream a locally stored mp4 video file. Media source name is "Video live file" and media file name is "vrettakos-new.mp4".
- Video audio streamed and recorded like it has continues mute/unmute slices.
- You can watch it here: https://youtu.be/kdt_fpD4_4E?t=2107. You can also hear the good parts before and after.
- Monitoring audio was fine.

Reproduction:
- I cannot reproduce the problem.
- It happens under no specific circumstances.
- It happens only when playing video stored locally.

Notes:
- Attached you can find the related log file.

Thank you in advance for your help.

1. Update your OBS and Windows per https://obsproject.com/blog/five-simple-tips-for-new-streamers
2. Audio buffering hit the maximum value. This is an indicator of very high system load, will affect stream latency, and may even cause individual audio sources to stop working. Keep an eye on CPU usage especially, and close background programs if needed. Restart OBS to reset buffering.
3. Run OBS as Admin

After making those changes, run log through Log Analyzer if still having same issue or post new log.
