Stream initialization error (OpeningDevice)

[Personuo]

When I run DeviceSelector scene, I immediately get this error Stream initialization error (OpeningDevice)

win10.
unity version 2021.3.4

Not sure if I'm getting something wrong, I'm not using any midi input device, I'm just trying to get the audio from loopback on windows.

I just download and run, no do anything

What audio device are you using?

[Personuo]

A normal realtek(R) Audio in my laptop integrated sound card.
I've tried cscore and fmod with no problems,both can detect the device and output spectrum data

In Lasp, the device is still found normally , although the error is always output. The device drop-down has my sound devices (both microphone and realtek(R) Audio).

[keijiro]

Is there any other processes (apps) using that audio device? Windows usually doesn't allow sharing an audio device between multiple processes.

[Personuo]

There should be none, when I restarted my computer and tried lasp immediately, I still get the error.
Then I am running the cscore and fmod projects and they still work well

[Personuo]

I mean, I don't have any external audio devices, only the sound card in the motherboard of my laptop.

My expectation is to play youtube music in the chrome and then unity can receive the data of this audio from loopback. (The music can still be played from my laptop speakers)

What happens when switching "Use Default Device"?

By the way, you can't do loopback with LASP. You have to install a virtual audio device app to loop it back to LASP.

yes, I found another desktop windows to test and it works fine but only searches for the microphone.
If so, then I will try other tools, thank you

@keijiro Hey Kejiro, same issue here; I have been using LASP for a while now without any issue I have no idea what causes this error now.. I don't think there is any other software using the audio device any idea on how to track that issue ?

Few more information, Unity 2023.1.16 (it was working with that version previously), on Windows 11, absolutely nothing else open, and same error for every device that I select, no matter the device ..

Many thanks

This issue was solved by giving Unity access to the microphone in the privacy settings of Windows 11.
