NOTE: This is more of a cautionary tale, than a critical bug report. It describes an obscure bug that appears to be caused by operators abusing the OBS-Studio software.

SYMPTOM: OBS-Studio .mp4 recording have no audio even though the VU meters in OBS-Studio indicated incoming audio
while the recording was being made.

HYPOTHESIS: If OBS-Studio (mac) is left running for very long periods of time it will sometimes make a recording with no audio.

SOLUTION: Don't do that!

We are running about a dozen instance of OBS-Studio Mac. It is installed mostly on Mac Minis and used for making recordings only (no streaming). These Minis are dedicated to running OBS-Studio and used for little else. We have had three instances of the recordings having no audio, despite VU meters indicating normal audio during the recording session. This has occurred on three different machines.

The log files for two of these events show that OBS-Studio was started days before the event and never restarted.
