Afraid not, but you can quite easily test by using a RawSourceWaveStream with an empty MemoryStream and a WaveFormat of your choosing to see what WaveFormat values your RDP session will allow. Obviously the RDP session must be set up to play audio as well.
You can also try searching through the forums here as you are not the first person to have issues with RDP.
