I had the same issue the first time I turned on my new replacement xbox and I have solved it.  Yes it is the "handshake" in a manner of speaking.  If you go into the Display settings there is an option called "Display Discovery" which is apparently turned on by default.  If you're running through a AVR, Surround Sound, a HDMI switch, or if your TV is just goofy, this discovery will not be able to complete the handshake with The TV as it does not have that direct connection.  For whatever reason, Microsoft decided in this scenario that the best thing to do is default to DVI mode...WRONG.  Anyway, just turn this feature off, it will tell you it needs to restart, do the restart, and you should hear the warm, comforting "vwoing" sound we are all so used to hearing, and it should default to 1080p.  You may have to turn your Audio settings back to Dolby Digital after this change. I think I did.

I have bought a new HDMI and it still didn't work until I read this.  This worked! Thank you for your help.

I also created an account just to thank you!  Worked perfectly after much head scratching and MS's site came up short.

Many thanks.

I have the exact same problem except mine has never worked properly. It's definitely not my cable - tried it on a PS3 and it worked fine. Using a 32inch LG LCD. Please someone... help?

Is it possible that you have the HDMI input on the TV set to a "PC" mode.  That really is the only thing I can think of.  I've heard of some LCDs having this problem when you put them into the mode designed for PC use over DVI>HDMI.  IE: they are not expecting audio over this connection (DVI = no sound) and instead pair the connection with an analogue or digital (optical/coax) input that may be expected to be coming from a PC.  I would guess that something like this is going on because you can see computer resolutions instead of normal 720/1080 settings.

Hi I have just had the exact same problem happen to me today and information on this issue seems very scarce on the net.

Did anyone find the problem or a solution to this?

I tried checking my tv option but I couldn't find anything and my SkyHD works fine through the HDMI port.

[itchy chode]

durr read the book the 360 doesn't output audio via HDMI

[jonbest]

Erm......yes it does.

It has been for the last 2 weeks, and my mates does. HDMI cables carry audio and video signals, thats a fact.

You only need the adapter if you want to connect it to a seperate audio system.

Google it if your not sure.

Now go and durr someone else instead of writing useless and completly wrong information.

I have the same problem.  When I first connected my 360 Via HDMI both video and audio worked.  Then I got an HD cable box and used the HDMI port for that.  I started using a VGA cable for the 360.  Then I went to switch back to HDMI on the 360 and the video options appeared as PC resolutions (Vice 720p, 1080i etc), and the audio didn't work at all.  I have been trying to google a solution, but I can only find other people with similar problems.  There has got  to be someone that has fixed this.

Its something to do with the HDMI handshake happening between your TV and the console. Some TV's will tell the 360 to allow PC type resolutions and some will only allow the typical NTSC resolutions. For example, on my Vizio LCD the 360 only allows me to select standard resolutions, but on my Olevia it shows me the PC type, although I get audio through the HDMI cable on both sets no matter what the resolution settings are.

Have you tried calling MS to see if they can help?

My sound stopped today during top spin 3.

Now no sound works at all. Even in the main menu no sound...

It almost worked perfectly for 1 year on this tv....

I am using HDMI with the arcade....
