audio-router VS SponsorBlock

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.

just use sponsorblock today, works fine on all my devices. https://github.com/ajayyy/SponsorBlock

from mobile phone to tv to pc.

You are one of today's 10,000.

And if you have android:

The SponsorBlock [0] addon has already solved that for sponsored/ad segments in videos. Rather than AI, crowdsourced timestamps lets it automatically skip past adverts.

For integrated ads on YouTube (sponsor messages), you can use the SponsorBlock extension (https://sponsor.ajay.app/). If you're using Android, you can also get NewPipe with SponsorBlock integration.
