Hi @Sozo,
There are some limitations in using FxSound over RDP if audio is configured to play on the local PC, because FxSound Audio Enhancer device will not be available. If in Remote Desktop connection, audio is configured to play on the remote PC, then FxSound can process the output. I had explained this in an earlier thread.
Can you please tell us about your audio playback configuration in RDP. Is FxSound quitting when you try to play audio on the remote PC over RDP? If FxSound running on the same PC, If you directly login on the PC?
