Wave error after first start

[teherauto]

Hello,

When I click on the "Render Lipsync to Action" button, the following error message appears:

Python: Traceback (most recent call last):
File "C:\Program Files\Blender Foundation\Blender 4.5\4.5\python\Lib\wave.py", line 283, in init
self.initfp(f)
File "C:\Program Files\Blender Foundation\Blender 4.5\4.5\python\Lib\wave.py", line 263, in initfp
self._read_fmt_chunk(chunk)
File "C:\Program Files\Blender Foundation\Blender 4.5\4.5\python\Lib\wave.py", line 388, in _read_fmt_chunk
raise Error('unknown format: %r' % (wFormatTag,))
wave.Error: unknown format: 65534

The video is a simple mp4 with AAC audio track.

I'm not sure what would cause that. It's related to processing the audio, so perhaps ffmpeg isn't installed properly? Perhaps try converting your clip to another format and see if that works.

This bug is in a third party library, so I'm not sure what could be causing it.
