No Audio Capture from Camo Studio/Camera

[bobdrad]

I am running OBS on Windows 11 and using Camo Studio, pairing it with my Android 16 phone using Camo Camera.
In Windows Volume Mixer, I can set the Sound Input device to Camo Camera, and it works fine. I can record and test the sound from the Volume Mixer (and from Camo Studio itself). So Windows and Camo are working fine together.

But in OBS, even if I add an Audio Input Capture Source set to Camo, I never get any audio input (Video capture is working fine). The source status is Active in the OBS Audio Mixer, and volume gain is at the default 100%. I have monitoring set to "Monitor only". But I'm not getting any input. I'm not seeing any input on "Desktop Audio" either.

Here is my current Log File: https://obsproject.com/logs/D4kH5UOcJhSiCiop
I need to get this working by this weekend, so any help would be most welcome! Thanks!

There lines from the log file look pretty suspicious:

11:01:15.711: [WASAPISource::TryInitialize]:[Microphone (Camo)] Failed to initialize audio client: 80070005
11:01:15.711: WASAPI: Device '{0.0.1.00000000}.{d9c5bc7c-a98a-40ca-bcfd-940bdce45f89}' failed to start (source: Mic/Aux)

Although it might be a red herring. I had tried using Global settings to add Camo as an audio input and mapped it to Mix/Aux. Later I removed that since I configured Windows to map it to the default input device, and I also created an Audio Input Capture for Camo directly. Neither Desktop Audio nor the Camo input Capture are producing any audio.

Closing on this - I found a solution. I added Camo in the Global Audio settings as Mic/Aux, and used that *instead of* "Desktop Audio".
So even though it was working in Windows as my input for Desktop Audio (I could test/play it directly from Windows Sound settings, and I could record/playback just fine directly in Camo Studio), when that was in OBS Audio Mixer it prevented any audio input (even when combined with Mic/Aux - I had to have Mic/Aux *only* in the Audio Mixer on that PC).
