Add multiple sound devices to guest

It should be possible to add multiple sound devices to a windows guest. So that the guest itself can decide where to put audio on.
Use Case: VoIP client software on windows should use the headphones, not the default speaker.

Currently (PD13) it is still not possible to add another sound device.

 

I am supporting this. For me it would be interesting in times of MS Teams and similar software where you can add a secondary ringtone which has no effect currently in guests cause all audio output is forwarded to a single device. I would like to hear ringing on my external speakers but have a call on my headphones without manually changing the devices on the Mac all the time.

 

Parallels 18, and still not support for multiple audio devices. Parallels team, I hope you're listening! Please add the ability to configure multiple audio devices (input and output)!
