ComfyUI-VideoHelperSuite\videohelpersuite\utils.py", line 172, in get_audio match = re.search(', (\d+) Hz, (\w+), ',res.stderr.decode('utf-8')) ^^^ UnboundLocalError: cannot access local variable 'res' where it is not associated with a value

How to fix it.

There's an error being thrown by ffmpeg when it tries to decode audio, which the current code was handling improperly.

I've pushed an update to properly expose what that error is, but you'll likely need to share what that new error message is.
