at some point the waveplayer stopped working. when doing a reconnection between waveplayer and audioout the tty renderer shows:
1 day 03:01:08 : Removing node: Default DirectSound Device from filtergraph

1 day 03:01:08 : Connecting from: WavePlayer (DShow9).Audio Output to: AudioOut (DShow9).Audio
1 day 03:01:08 * : nil pins can not be connected in directshow graph
what can this be?
