Is audio required for a run to be accepted ?

I believe I have seen runs that don't have audio before, and nothing in the game rules states that audio is required. I would wait for a mod's input just to be certain, but I don't think it is necessary.

I don't think. I understand the video without audio, but audio without video? I don't think it would be accepted

Normally most games would require game audio to prevent any spliced or cheated runs. But I don’t think you would need game audio but if I were you, I would highly suggest you include game audio.

Game audio is not required, but please have it on if you have it available. It makes it easier for us to verify the run.

Also, I can add a rule requiring in-game audio if the community would like that. If it happens, I'll keep the runs that were verified before the change.
