Hi there, I'm a music producer and regularly integrate RDP into my workflow for using different machines for different purposes in my studio setup.
One really severe issue is passing Pro Audio over RDP. There must be a bitrate/sample-rate mismatch because there's severe aliasing/digital artifacts that occur when playing any 24bit-48kHz audio (the defacto standard for audio production).
We are currently forced to use 3rd party solutions like AudioMovers, for an unintended purpose. It's a lot of extra logistics (and cost) when RDP could simply pass proper 24bit/48kHz audio as an option for those who want it!
A virtual ASIO driver would also be pretty unreal, but let's start with the above as a consideration.
