Hi guys

Im a newbie in this HTPC field. infact, this is my first try of creating HTPC. 

I have a compaq PC, running AMD Athlon 64 X2 3800+ with 3GB of RAM  

I have replaced the GForce video card as it was a dud with ATI Radeon HD4670 with VGA, DVI, and HDMI out

I have tried the VGA output and it is working properly, have not tried the DVI as I have no DVI monitor, only have HDMI monitor

I have disabled the onboard audio on the bios, but still no audio through hdmi, let alone video

I have pretty much tried every setting possible

Have downloaded the latest driver for the Radeon too

Any idea guys ??

Desperately need help...

Thanksss...

PS : I'm using my pioneer plasma 508xg in the lounge as the monitor

After disabling the onboard audio in the BIOS, have you opened Control Panel | Sound to select the HDMI audio as the default?

I had the same problem. You need to go to Realtek dot com and get the Realtek HDMI audio drivers.
Thsi will enable the 7.1 audio drivers on the card

And have you turned the TV *BEFORE* turning on the PC? Waited for the TV to initialise before starting the PC?

you'd need the 2.50 and 2.49 drivers from http://www.realtek.com/Downloads/downloadsCheck.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTyp...

When I bought my Dell Zino HD to be my Media Centre the HDMI didn't work out of the box - no video or sound. Dell sent a technician with a replacement motherboard and video card, but it was the wrong model.

Strangely, after refitting everything HDMI started working. We were both surprised - it could only be something wasn't seated correctly before, or the BIOS was reset when he removed the battery.

I had no problems since. Perhaps you could try removing the card, resetting the BIOS and then reinstalling it?

did the computer detect your hdmi device (amp/tv/monitor) straight off or did you have to force activate to send signal? if you had to force then it doesnt send sound as it never detected the hdmi cable. to find out does the sound mixer show green bars bouncing up and down ie sound is being sent or just a dull grey bar ie no sound is sent, change your hdmi cable etc to get it to detect the cable

the sound mixer shows green bars bouncing up n down right away when the sound is sent via hdmi

didn't force it

computer can't not detect the plasma monitor connected via hdmi, only the small monitor connected via vga

if there is no detection then where is the problem?

- dud motherboard
- dud graphics card
- dud hdmi port
- dud hdmi cable
- dud tv

i'd say most likely cable - i had the same problem tried 2 hrs 2 reinstalls no detection no sound then tried another cable and there it was. (but in my case no green bars only grey bar)
