Hi,
I have just built up a new htpc system with an MSI 785gm-E65 mainboard. Running under Win XP prof SP3, Mediaportal 1.1.0 RC4 and Catalyst video driver 10.5. The system also works as a file server and runs 24/7.
I have connected the htpc to my Sony KDL32W5720 only via hdmi cable. Everything works well (audio and video) as long as I do not switch the TV off. After switching off and on again, I get no picture, the screen is black. After removing the hdmi cable and plugging in again, I sometimes get a picture again, but not always. Now I found out that it helps to make a second connection with an dvi-hdmi adapter cable from the dvi port of the motherboard to an unused hdmi connector on the TV. With this setup I have a working solution when switching the TV off and on. i could live with this as the cable is only ~€5 and I do not mind the second cable.
But with this setup i have a new problem. Now after rebooting the PC, I have no sound on the TV! Looking into the hardware manager, I see that the previously existing 'ATI hdmi' hardware is missing now. The video on the hdmi output still seems to work (as I have a picture on the TV) but no sound.
Does anyone have a clue how this could be solved? Is it a problem in the BIOS or the software drivers or even the TV set? Or possibly a problem connected with the Catalyst? I hav absolutely no idea.
BR,
Jörg.
PS: I had a system running with an Asrock ION330 system before, also using only hdmi and this worked perfectly.
Edit: problem solved If I use only the dvi-hdmi cable I get picture and sound also after rebooting and switching the TV off and on again. I am pretty sure that I have tried this before, but nevertheless, now everything is working!
