I have a Mac Mini as an HTPC. I have 2 HDTVs, livingroom and bedroom. The livingroom is connected with Mini DVI to DVI to DVI-HDMI to HD A/V Receiver with TOSLINK Audio from Mini to A/V Reciever. The bedroom is Mini DisplayPort with USB Audio Adapter to HDMI cord. The audio works, but doesn't play in both rooms at the same time. I have to use SoundSource or System Preferences to switch between USB Audio and Digital Out, depending which TV I am using. I know that's not a huge chore to do each time, but I am trying to make this as easy as possible for my girlfriend and friends. And also it would be cool to have audio playing on both when we have parties. Is there a way or app that forces audio output via Digital Output and USB at the same time?
