Play audio to multiple output devices

[Zhabha]

Hello,

would it be possible to implement the functionality to play the same stream in two different output devices? Or possibly play different streams from same file to different outputs?

I've found out some workaround using Audio Virtual Cable software, but that's not exactly free, so I'm searching for alternative. Also some other players offers the possibility to play multiple streams, they are played to the same output device.

In my case I can imagine two scenarios, in both cases I'd like to have the sound going to both my 7.1 headphones (connected via external USB sound card) and my TV connected via HDMI or integrated stereo speaker on my laptop. It would enable to enjoy the premium sound quality my headphones offers (in both surround and stereo modes) and still allow the rest of the family to watch the movie with the sound from TV.

1] video file with single 5.1 / 7.1 audio stream
- surround sound will go as is via external USB sound card
- surround sound will convert to stereo and will go via HDMI to TV or to integrated speakers
2] video file with multiple audio streams
- surround stream will go to external USB sound card
- stereo stream will go via HDMI to TV or to integrated speakers

Thanks in advance

SO far, it is not possible, indeed.
