I recently bought a computer and installed an ATI Radeon 4650 graphics card. I use the HDMI connector on the card to connect to my TV. The video works beautifully, but I noticed that sometimes my sound stops working for some reason. I have to unplug the HDMI cable from my computer and plug it back in in order to get the sound to work again. Does anyone know why something like this is happening? This is really annoying since I am using my computer as an HTPC.

Thanks in advance for any help provided.

Check your audio options (Control Panel -> Sound) where you should have SPDIF output enabled.

Three important things to get the sound on ATI 48XX cards HDMI connection to TV

1) Use ATI DVI-HDMI converter. Then connect the HDMI cable from video card to HDTV
2) Go the control Panel SOUND OPTION. Select ATI HDMI Output as Default Playback.
3) The sound or Audio is assigned to the PRIMARY DISPLAY. The HDTV must be designated as PRIMARY DISPLAY. This can be done on CCC.

The above should take care of it. Take note that this assumes that your software /driver installation for the ATI video card is correct.

If your driver installation & bios settings are correct. Using the Device Manager /(Sound, Video & Game Controllers) you should see "ATI High Definition Audio Device."

On the Sound Option at the Control Panel you should see "ATI HDMI Output"

CCC is the ATI Catalyst Control Center

The ATI Radeon 4670 graphics card is the only display.

The ATI Radeon 4670 graphics card is NOT the display. Did you have the HDTV attached when you were looking at CCC?
Also look in Control Panel and see what Display info/properties is there.

In this CCC screenshot the ATI Radeon HD 4350 is the video card and the Sony TV is the display.

I have the same problem. I have the HIS 4650 AGP, it has a native HDMI and when I try to install the HD audio driver it ask to reboot and then I don't see it anywheres in my system? Anyone else getting this wierd install problem? I don't know what more to do? I'm going to try and boot in safe mode and reinstall the driver. I'll be back to see if this fixed the problem.
