Describe the Bug
On Mac M1 as host, audio won't work, clients does not receive anything
Expected Behavior
I'm expecting the sound thrown at the the "audio sink" to be transmitted to the client.
I've linked my complete, log, but I think this particular line is of interest :
Warning: audio_control_t::set_sink() unimplemented: BlackHole 2ch
Additional Context
The documentation states
Sunshine can only access microphones on macOS due to system limitations. To stream system audio use Soundflower or BlackHole.
BlackHole is running, I've been able to test it, there is no issue there.

Same issue. I found it is not implemented for now on MacOS. https://github.com/LizardByte/Sunshine/blob/master/src/platform/macos/microphone.mm#L47
However, I guess it is implemented by using microphone to redirect audio to sunshine. It maybe a misconfiguration but I have't found any config for this. https://github.com/LizardByte/Sunshine/blob/master/src/platform/macos/av_audio.m#L108
OBS is able to capture macOS system audio natively using Apple's ScreenCaptureKit, without Soundflower or BlackHole. Is there a potential to have a similar kind of integration in sunshine?
Screenshots from OBS:
And the relevant OBS source code / headers appear to be the files starting with the mac-sck-* (ScreenCaptureKit) prefix in the mac-capture folder: https://github.com/obsproject/obs-studio/tree/master/plugins/mac-capture
@vgmoose probably. I don't think the ScreenCaptureKit existed when this was first introduced into Sunshine. We would gladly accept a PR for this.

is there actually a way to get audio to work? I also tried with blackhole without success. The web interface claims we should be able to use blackhole or soundflower but how exactly?
@Tomahawkd @ndesgranges I managed to get it to work. You need to match sample rates for BlackHole input and output to 48kHz. Be sure to type "BlackHole 2ch" manually into Configuration. Restart the system if needed.
