Hi Mandelmantis!
Good problem description, I see exactly what’s going on.
Breakaway only catches audio that comes from programs – not from the sound card.
Your TV card isn’t playing the audio through Windows the way normal programs do – instead, feeding it directly to the sound card. Therefore, it completely bypasses Breakaway.
The only workaround solution I could think of would be to use a separate program to get the audio from the sound card input, and then play it into the Breakaway Pipeline, so that Breakaway can intercept it and send it to the sound card output. However, this will likely cause too much delay to be usable.
I’ve seen some TV cards where it’s possible to choose what route the audio should take — either directly to the sound card, or through DirectSound (which means it’d be going through the Windows). If there is such an option on yours, then that should take care of it.
