Ive seen that many are having the problem I have had recently. When using HDMI Dolby Digital output is iffy, sometimes it would work and sometimes not. I found a solution that has worked perfectly for me. First off I have tried this with the HDMI attached
to my tv with a SPDIF/toslink output from the tv to my 5.1 reciever and also with the HDMI plugged directly into my receiver. This solution has worked for both setups. The problem for me was the "Auto Detect Display" option under the XBOX Settings>Display
Settings. With auto detect on Dolby Digital was hit or miss. When I turned off the auto detect option under the display settings everything works perfectly. It seems that when auto detect is on if your hardware is not fully recognized or supported then it
sometimes defaults to stereo regardless of if the Dolby Digital 5.1 setting is enabled. By turning auto detect off in the display settings seems to allow you to override all the settings associated with auto HDMI, thus allowing you to force Dolby Digital 5.1
output. I hope this is helpful to everyone who has had the same problem.
