Enable audio on remote Windows computer through xfreerdp

I'm using xfreerdp to login to a windows machine (runnning windos 7 64bit) on my desk next to my linux machine (running RHEL7). Normally I use: xfreerdp -k uk -g 1280x950 --no-nla --plugin cliprdr Which leaves the audio disabled. I can forward the sound output from the windows machine to my linux box using: xfreerdp --plugin drdynvc --plugin rdpsnd I cannot use the linux microphone device to supply audio to the windows box. I tried: --plugin audin_pulse and setting the registry entry: HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp fDisableAudioCapture to 0. I'm not sure how to fix this problem, despite looking at similar questions here. However, the windows box is on my desk so I would be perfectly happy to have use the headphone and mic sockets there instead. **That is I don't want to forward the audio at all just leave it enabled on the remote machine**. Remote desktop seems to disable it (on the windows side I think) by default . Under the old rdesktop program I was able to run -r sound:remote or -r sound:local to do this. What is the equivalent on xfreerdp? [Background: I am aiming to use skype for business on the windows box. It doesn't matter where I plug the headset in as long as I can get it to work. I do have pidgin+sipe working on the linux box but I'm not certain all the features will work]
