I know a video from roughly 11+ years ago where the audio got messed up, not sure how to even begin to report that. Was some niche "inside joke" type of meme. I have to wonder how many videos got re-encoded by YouTube that got screwed up inadvertently.

yt-dlp https://github.com/yt-dlp/yt-dlp https://github.com/yt-dlp/yt-dlp lets you list and download different formats offered by YoTube for videos. You could try downloading different audio formats and see if any of the available ones contain non-garbled audio. For example: yt-dlp -F "https://youtube.com/watch?v=a28_aXgrgXE" Output: [youtube] Extracting URL: https://youtube.com/watch?v=a28_aXgrgXE [youtube] a28_aXgrgXE: Downloading webpage [youtube] a28_aXgrgXE: Downloading ios player API JSON [youtube] a28_aXgrgXE: Downloading player 62ccfae7 WARNING: [youtube] a28_aXgrgXE: nsig extraction failed: Some formats may be missing n = l9bNLKrDBBdCJtknGqU ; player = https://www.youtube.com/s/player/62ccfae7/player_ias.vflset/en_US/base.js WARNING: [youtube] a28_aXgrgXE: nsig extraction failed: Some formats may be missing n = Z-MlQqu4ClRjI62sqw_ ; player = https://www.youtube.com/s/player/62ccfae7/player_ias.vflset/en_US/base.js [youtube] a28_aXgrgXE: Downloading m3u8 information [youtube] a28_aXgrgXE: Downloading MPD manifest [info] Available formats for a28_aXgrgXE: ID EXT RESOLUTION FPS CH │ FILESIZE TBR PROTO │ VCODEC VBR ACODEC ABR ASR MORE INFO ────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── sb2 mhtml 48x27 1 │ mhtml │ images storyboard sb1 mhtml 33x45 1 │ mhtml │ images storyboard sb0 mhtml 67x90 1 │ mhtml │ images storyboard 233 mp4 audio only │ m3u8 │ audio only unknown Default 234 mp4 audio only │ m3u8 │ audio only unknown Default 139-dash m4a audio only │ 427.60KiB 48k dash │ audio only mp4a.40.5 48k 22k DASH audio, m4a_dash 139 m4a audio only 1 │ 427.60KiB 48k https │ audio only mp4a.40.5 48k 22k low, m4a_dash 140-dash m4a audio only │ 853.17KiB 96k dash │ audio only mp4a.40.2 96k 44k DASH audio, m4a_dash 251 webm audio only │ 851.41KiB 99k dash │ audio only opus 99k 48k DASH audio, webm_dash 140 m4a audio only 1 │ 853.17KiB 95k https │ audio only mp4a.40.2 95k 44k medium, m4a_dash 160 mp4 108x144 30 │ ~962.40KiB 108k dash │ avc1.4d400b 108k video only DASH video, mp4_dash 269 mp4 108x144 30 │ ~ 1.43MiB 164k m3u8 │ avc1.4D400B 164k video only 278 webm 108x144 30 │ ~846.56KiB 95k dash │ vp9 95k video only DASH video, webm_dash 133 mp4 180x240 30 │ ~ 2.11MiB 242k dash │ avc1.4d400c 242k video only DASH video, mp4_dash 229 mp4 180x240 30 │ ~ 2.65MiB 305k m3u8 │ avc1.4D400C 305k video only 242 webm 180x240 30 │ ~ 1.92MiB 220k dash │ vp9 220k video only DASH video, webm_dash 134-dash mp4 270x360 30 │ 3.32MiB 459k dash │ avc1.4d4014 459k video only DASH video, mp4_dash 230 mp4 270x360 30 │ ~ 5.07MiB 583k m3u8 │ avc1.4D4014 583k video only 134 mp4 270x360 30 │ 3.32MiB 380k https │ avc1.4D4014 380k video only 240p, mp4_dash 243 webm 270x360 30 │ ~ 3.53MiB 406k dash │ vp9 406k video only DASH video, webm_dash 135 mp4 360x480 30 │ ~ 10.05MiB 1155k dash │ avc1.4d400b 1155k video only DASH video, mp4_dash 231 mp4 360x480 30 │ ~ 11.43MiB 1313k m3u8 │ avc1.4D400B 1313k video only 244 webm 360x480 30 │ ~ 6.55MiB 753k dash │ vp9 753k video only DASH video, webm_dash And then download each of the "audio only" entries from the table.

It might be worth to be careful about downloading alternate format versions of too many videos. I could imagine that downloading alternate formats of too many videos from YouTube could trigger something on their side to make them think you are a bot or something. Of course that's just speculation and I don't know if YouTube actually does that. Hopefully doing it for a single video won't get your IP banned by YouTube.
