Issue with audio not being recognized to create auto transcript

I’m trying to transcribe a sequence, but Premiere keeps saying “No dialogue found” even though the clip clearly has spoken audio.

• Audio meters are active and levels are normal
• Clip is not muted and is on the timeline (A1)
• I’m using Transcribe Sequence (not static transcript)
• Tried tagging audio as Dialogue + different settings
• Reinstalled Premiere and cleared cache
• Still happening across multiple projects

Footage is a .MOV file, audio plays fine — it just won’t generate a transcript.

Has anyone run into this or know a fix?
