Im a newbie to HTPC. Have a Gigabyte GA-970A-D3 AM3+ MB and a HIS Radeon 6670 video card and run Windows 7 Pro.
I connected a Mitsubishi Diamond series rear projection TV with an HDMI cable and found a few issues. The audio was delayed, maybe tens of seconds, and the video has digital noise; white pixels, lines, black turning white.
Tried connecting a Panasonic Viera TV and it would not recognize the signal, tried reboots with the TV in. Used the DVI output from the HTPC into the HDMI on the Pan TV and then RCA audio in from the headphone jack output and it works. But, I would like to set the HTPC up with the HDMI in the end.
I ran a scan with a few driver scan programs. Most show these three drivers as out of date; ATI HDMI Audio, Realtek High Definition Audio, and ATI I/O Communication Procedure SMBus Controller. I have tried updating the drivers through the device manager and either updated or had the drivers show as up to date. However, run the driver scan and it still shows them as out of date. I have tried uninstalling and reinstalling from both the internet and the original discs without success.
It seems that I have issues and so do my drivers. If I knew the driver scan services would surely fix this it, at this point it would be worth the $29.95. So far when I try to find the drivers I find scan software rather than the drivers and I am not sure exactly what I need.
A sure remedy would be great advice. Since I am a newbie even some advice on driver websites and troubleshooting would be helpful.
