Screen + Microphone + Speakers (and possibly Speaker recording in general) fails to record Speakers

[michaelsmoody]

Platform is Edge on Windows 11. Confirmed on Edge on macOS as well. Up until recently, this was working.

(I thought it was due to my use of AirPods, as I was constantly getting garbled audio in some recordings! But no, a short recording just now with no external audio devices on a different device with a fresh install of Edge on Windows 11 confirms it is RecordRTC)

Setup:

1. Setup an Audio In/Out Source (Perhaps a Zoom Session as that's Audio In and Out, with something interesting on screen)
2. Start Recording with "Screen + Microphone + Speakers"
3. Share Window (*1 please see note at bottom) with RecordRTC
4. Generated Audio in the Session (both In/Out)
5. Stop Recording
6. Download Recording
7. Playback Recording and Note only Microphone Audio

Note MISSING SPEAKER Audio in Recording.

Expected Behavior: Both Microphone and Speaker Audio should be present in Recording.

I will confirm if this is no longer working in Chrome as well.

*1 (rather than share a Tab, which also fails, but never consistently worked. Sharing by TAB causes the speaker audio to be routed to RecordRTC in an odd way, which while it still doesn't work means I also cannot hear it....it's an odd behavior)
