How can I use a usb audio device on my server with Duo? (so I can use voice / headset via usb on my host pc)

[leshokunin]

I've been looking for a good solution to use a microphone while gaming online. Since Moonlight isn't good at handling microphones, I've resigned myself to directly plug my USB audio dongle to the PC (I can always use BT for the Mac).

Hardware: I use my Mac as the client, and PC as server. 10GbE local network.

Problem:

• while my main Windows account sees the dongle, the Duo user only has “remote audio sink“ as the audio output, and nothing for audio input. I've tried installing drivers or clicking to see disabled audio devices, no luck.

How can I use a usb audio device on my server with Duo?

Try VirtualHere

I know it doesn't work from a Mac client to PC host (Mac seems to not handle mics for this). Do you mean VirtualHere from main Windows user to Duo user?

You should download the VirtualHere client on your Windows PC (on the same user account you use for Duo instance) and the macOS version of the VirtualHere server on your Mac (outside of Duo). Once connected, any device you plug into the Mac should appear as if connected directly to your PC.

I haven't tried this on Mac, so I'm not sure if there are any limitations that prevent this from working.

I also never tried running VirtualHere client-server on the same Windows PC using Duo+Host so can't tell you whether that would work.

That's for the client of macOS. You want the SERVER to run on your Mac while the CLIENT runs on your Windows PC.

Interesting idea. Let me see if I can!

Just tested it. I ran the server on the mac, shared the headset. The PC client sees it, and I can click use.

However, no new audio device shows in the sound settings. Only the remote audio sink. Same as when I tried plugging directly to the PC via usb, or via bluetooth. Seems Duo only wants to have this one device.

Have you tried setting the USB dongle as the audio sink for Sunshine? With the dongle plugged directly into the PC, open the Sunshine folder within Duo folder then navigate to Tools > audio-info.exe and open it with cmd. Find the audio device you want then copy its ID and paste it into the Audio sink option in the audio section of the settings in Sunshine web portal. This works with the official Sunshine build, I'm not sure whether Duo changes anything about it so changing the sink might break the audio.

Note that "Mute host PC speakers while streaming" in Moonlight settings should be disabled.

Do you think that would enable the microphone too though, or simply stream the audio from the usb dongle? I'll give it a go in a bit.

I don't see a audio-info.exe in the tools folder. I simply did a regular install. Any idea? Maybe I can get the exe somewhere, or find the info by hand?

Some more info: I am not able to add any audio device when I'm in the Duo user. I can totally do it when I'm the regular admin though.
