Provide a description that is worded well enough to be understood

The latest fix for drtv have introduced a new issue. Audio formats are listed with m3u8 extension instead of m4a.

This causes audio only downloads to be saved with m3u8 extension, and when downloading video+audio it merges to mkv instead of mp4.

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
• If using API, add 'verbose': True to YoutubeDL params instead
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below
