I connected my TV with computer with DisplayPort -> DVI -> HDMI adapters.
Everything works fine exept sound. Since Thinkpad T500 doesn't support sound over DisplayPort (and I have DVI connector between), I plugged analog sound to TV with computer headphone output.
But TV doesn't read analog sound input, becaouse I think it recives some audo singnal from HDMI.
So I need your help and advice to disable sound singnal output through DisplayPort (X recognises it as HDMI-1)
Here's my video card configuration in xorg.conf:

I think it's not hardware related issue, because it works on Ubuntu 8.04 on same computer.

That would be funny... X has never been known to handle audio before .
Alsa handles the sound (or OSS, whatever your preference is), so configure your sound server for the audio.

I put !snd in rc.conf to disable sound completely.
Then I sent audio to my TV from another device, but it still doesn't read analog:(
There's a solution for nVidia drivers to set custom EDID (http://www.nvnews.net/vbulletin/showthread.php?t=128507).
But Intel driver hasn't that option:(

I finally figured this out:)
The problem was in Intel driver (since version 2.6) when HDMI audio was enabled in G(M)45 card (commit log here http://cgit.freedesktop.org/xorg/driver … 8dc54a9a1)
I took the latest driver and changed a little code. Then compiled it and everything works fine:)
I'll post a bug to freedesktop.org to keep up with updates in future without recompiling.
