audio-router VS iina

Audio router

I imagine Audio router might help in what you're looking for.

The ones that people recommended that I could still find (both of which are at least 7 years old): https://github.com/audiorouterdev/audio-router https://vb-audio.com/Cable/index.htm

I personally use Audio Router, you can look up guides about how to set it up fairly easily.

How did you used to route audio from YouTube to Audacity? Mac's require something like Blackhole to do that. Maybe try something like https://github.com/audiorouterdev/audio-router

https://github.com/audiorouterdev/audio-router and some virtual cable device?

If Voicemeeter can't force it, you can use this one, so you can select the output for the specific app. But you'll still need Voicemeeter or Virtual Audio Cable

One program you can test is Audio Router. It can't mess up anything, but it also has not received any updates in over 6 years so it's not uncommon for it to not work with certain devices or programs.

9. IINA

While QuickTime Player is still supported, it's not in a good state imo. I've never found chapters to work, for example, and have had other issues like the app complaining about being "busy" when trying to trim a video. If you're willing to explore, I'd suggest trying out IINA instead. It doesn't support editing, but it's good at playing.

Well, there is not much for Mac, there is this https://iina.io

IINA - Price: Free Modern media player for macOS that supports almost all video and audio formats.

This has been my go to for years: https://iina.io/

IINA - media player.
