Is it true that the PS3 will only output 2 channel PCM audio over HDMI? I have a Toshiba HD-A1 HD DVD player connected via HDMI to a Yamaha 5990 receiver which works fine with both HDMI video and 5.1 audio. However, when I connect a PS3 via HDMI (using the same settings on the receiver as the Toshiba) it only shows 2 channels of audio. The discs used for the test was the BD Flyboys and Phantom of the opera. My PS3 is running the version 1.31 firmware out of the box. Haven't had time to update yet.
