So there's no way to capture internal audio from chrome?

I've been tearing my hair out trying to get my internal audio recorder app to work with Chrome and I wanted to confirm if I've hit a hard wall.

I'm using the AudioPlaybackCaptureConfiguration API. It works perfectly for games, YouTube (native app), and Spotify. But for Chrome it captures absolute silence.

My findings so far:

The API strictly allows USAGE_GAME, USAGE_MEDIA, and USAGE_UNKNOWN.

It seems web-based calls in Chrome use USAGE_VOICE_COMMUNICATION, which Android strictly blocks 3rd-party apps from capturing (anti-wiretapping privacy features).

Even regular video playback in Chrome often fails compared to other browsers like Samsung Internet (which works fine).

Is there any obscure workaround, attribute, or manifest flag I'm missing? Or is Chrome simply a black box for AudioPlaybackCapture without root/Magisk?
