One way- I’d suggest creating a duplicate program and new bin.
Identify and highlight each offending clip and “change media attributes” (MediaMenu) to reflect the proper input setup audio level. When done save the duplicate program.
Then 1 by 1 drag each offending clip into the bin.
Then open each clip in the edit suite and deactivate the video box and hit apply.
Your bin should have a bunch of audio only clips. Select all and delete clip & media. I’d leave the audio files in the trash til after the next step.
Select the duplicate program and batch redigitize.
Good Luck.
