I'd like to use the microphone forwarding over RDP on Win7 Pro. Unfortunately this is only available on Enterprise and Ultimate editions. Do you know of any workaround for this?
I'l like those workarounds to be free if possible
You might be able to enable it by changing the value of this registry subkey:
HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\fDisableAudioCapture
To enable audio redirection change its value to 0
.
