PCM audio over HDMI

Hi,

I'm trying to find out if the Xbox 360 will output PCM stereo or surround audio through the HDMI. It doesn't seem to be working but I just wanted to make sure it wasn't me! I can't seem to find out a definitive answer.

Cheers,

Dave.

If you switch it from Dolby Digital 5.1 to Digital Stereo, it outputs PCM.

This doesn't seem to work. Something I've got wrong sorry, is it's actually outputting to DVI as I'm going from HDMI to a DVI monitor so it's detecting the DVI connection not the HDMI signal.

DVI doesn't support audio.

Yes I understand that.

I think that there is more to it, I should have mentioned before. The setup is this. I'm connecting the Xbox to a cinema projector that only has a DVI connection not a HDMI connection. I'm also going through a box to extract the audio from the HDMI signal to send it to the amps.

I'm going HDMI from the Xbox to the audio stripper box which then passes the PCM audio to the sound amps and outputs the video through HDMI which I have going into the projector using a HDMI to DVI cable.

The Xbox is displaying it's outputting DVI in the settings not HDMI. Is there a way to 'trick' the Xbox at all? I'm guessing there isn't. Also as it's stating it's outputting DVI I'm assuming it's not sending the audio too, which is why I'm not getting any audio.

Check the resolutions listed in System Settings. If you're seeing X by Y values like 1920x1080 and not 720p, 1080i, and 1080p, then the box you're using isn't HDCP handshaking with the 360. You'll probably have to resort to either using optical or using the thin A/V adapter alongside the HDMI port and the left/right audio outputs it provides.

Yes it's giving a resolution of 1920x1080. I'm currently using the thin A/V adapter technique you mentioned just fine but I wanted it to work with our existing audio system. No worries, I'll do something with the audio setup instead. Thanks for clarifying it though.

There are HDCP-compliant switches that can output analog audio. Monoprice sells one.
