Feature request for loopback of output device.

[HaujetZhao]

I know that same kind of issues has been made and got negative answers.

The last one seems to be #287 and is was in 2020.

But I found that in 2022 the WASAPI loopback had been implemented in PortAudio/portaudio#672 , so maybe introducing loopback into sounddevice seems possible now.

This has indeed been implemented in PortAudio, but there hasn't been a release since. We're waiting for that.

You can compile your own DLL from the development version and use that.

I know that same kind of issues has been made and got negative answers.

AFAIK, this has never got negative answers, we were always waiting for PortAudio.

Oh, sorry, my stereotypes made me think there should have been a few releases of PortAudio since it's been a year from that PR, turned out it hasn't.

Hi! How is the status on the loopback? I was kind of surprised to see no official release of neither pyaudio or sounddevice has incorporated it yet.

@enriicoo Nothing has changed since my comment above: #510 (comment)

Would be great if we have the loopback option for wasapi implemented. Portaudio has it now. Not sure who can help in sounddevice. It does'nt appear as an audio device.

@parthiv91

Portaudio has it now.

What do you mean by that?

AFAIK, there still hasn't been a new PortAudio release.

If you want, you can try the DLLs from this branch (built from PortAudio's master branch): https://github.com/spatialaudio/portaudio-binaries/tree/portaudio-master
