Yes, you should have audio.
Go to the Audio Control - RSOIP tab on the server side and see if the level meters move and the level controls are up on the Capture side. If good then check the Client side Audio Control - RSOIP tab Playback side. The level controls should be mid position. Do you see the level meters move?
