I added a Denon CD Receiver (AMP) to one of my 7MC PC’s today to power some in-room speakers. I used the analogue stereo 3.5mm port on the back of the motherboard to the phono line in Left / Right ports on the back of the Denon amp.
I then needed a way to be able to change the default windows audio device from within the Media Center user interface, (Speakers) audio device for the Denon amp and (HDMI) audio device for the HDTV.
I tried to do this in the past using Vista Audio Changer but found it didn’t work 100% as it would minimize Media Center and then using a macro open the Playback audio devices dialog box and change the default audio device, it was hit and miss to say the least.
I then found a Windows Media Center add-in called Audio Renderer Updater on this page here. I installed it today on one of my 7MC PC’s and it works great, no minimizing of Media Center or any of that malarkey, it just switches the default windows audio device perfectly every time!
