AI Multicam SmartSwitch does not cut the material.

While working with the AI Multicam SmartSwitch feature in DaVinci Resolve, the system is unable to automatically cut video material based on audio. The issue occurs when editing a conversation between two people recorded using three cameras.

Equipment configuration:

- Camera A: Records audio from two lavalier microphones, each on a separate channel.
- Cameras B and C: Record audio only using built-in microphones (used for synchronization).

External tools handle this material without any issues.

I'm experiencing the exact same issue using the AI Multicam SmartSwitch feature. In my case, it's a podcast setup with:

4 cameras

5 external audio sources (4 lav mics + 1 room mic), all recorded via a Zoom H10

I'm working with DaVinci Resolve 20 Beta 2, and the system always freezes at the same point during the audio-only cut process — no error message, just a progress bar that stops around 25%. I’ve tried multiple sync methods, separate timelines for each camera, and replacing in-camera audio with the external audio. Nothing worked.

This tool would be incredibly useful for automating edits in long-format talk shows and podcasts. Hope Blackmagic can look into this bug soon.
