My wife turned on our Xbox yesterday and after starting up, was prompted to download an update. After installing the update, we lost all sound to my AV Receiver.
My connections are as follows:
• XBox 360 (Halo 3 Edition) connected to Yamaha HTR-6130 via HDMI
• Yamaha HTR-6130 to Panasonic LED LCD TV via HDMI
Prior to the update, we never had any trouble with the XBox outputting Digital 5.1 surround to the receiver via HDMI. After the update, I only get sound via the Digital Stereo setting, passing through to my TV. Setting the Audio to any other digital setting causes complete loss of sound, receiver and TV.
I've checked and double checked all other connections and settings on my devices (TV, XBox and Receiver) with no luck.
I don't know if this is a bug with the update or a new HDMI handshake problem with my receiver.
Any help is much appreciated!
