Tested many ways to achieve this including nomachine and windows remote desktop. Audio was always garbled or worse. We use vb-audio potato and the VBAN talkie app to send the mic audio to Radioboss and recieve audio back from Radioboss. It works very well. You can still use a remote desktop of your choice, just disable its audio features.
Tip, use ASIO drivers where possible (Windows remote desktop wont disconnect ASIO drivers when connecting/disconnecting)
