Bear with me on this one. I have a Windows service which can play .wav files for alerting. As long as the computer has a sound card and speakers, it works fine.
There is also a GUI that lets the user choose which sound that the service will play. When the user is connected via Remote Desktop to the GUI and tests the sound, he hears it on his PC (because he's indicated audio should be redirected to his PC). Works great.
BUT, when the service plays a sound, it does not get redirected. My initial thought was that the service was running as a separate account, and thus a separate WinStation. But he is running the service as the same user that is using the GUI. But still no sound forwarding.
I suppose this might be impossible -- the service might still be in a separate WinStation even though it's using the same account. Is there any other way to get that service to forward its sound via RDP?
