hi,

i have a custom built PC with a GIGABYTE EG45M-DS2H mobo and whenever i try to use the onboard HDMI port with my new LG flatscreen, i see a picture but there is no sound. Windows says its going to my onboard realtek audio. i remember when i used this before it worked fine but now the audio doesnt work. I updated my intel G45 chipset/graphics driver and the Intel HDMI Audio Driver. is there anything else i need to check to make this work?

BTW im running Vista Ultimate SP2 64-bit

Thanks.

the resolution change didnt fix it. i just dont understand my realtek card is "overpowering" the intel card powering the audio for HDMI, not letting it be recognized as an audio output device. (dev mgr says otherwise)

anything else i can try? is this surely a windows issue? if i stick my XP HDD in my machine will it work again?

Thanks.

Is that what I need even though my hdmi port is apart of my chipset hence made from intel not ATI? I will still give it a shot alhough I nevr did this b4. all the drivers loaded with the chipset installer.

Thanks. I'll get back to u on what happens

I was distracted by the Sapphire reference, sorry.
The only other thoughts on this seems to be;
Load the Motherboard drivers first, then the Realtek hdmi drivers (not clear if you also need the Microsoft UAA drivers).
Then verify this setting;

In Windows Vista, select Start>Control Panel>
Sound, select Digital Output Device (HDMI) and
then click Set Default.

i misread things all the time.

chipset drivers are loaded and drivers for all other peripherals on the board are also loaded.

Realtek does not supply the driver for the HDMI, intel does. Regardless, that driver is also loaded fine.

UAA is only needed in Win2k and WinXP. It is already included in Windows Vista and Windows 7.

Went into the Control Panel in the sound options. The only 2 choices for sound output are Realtek Digital Output (the one that is selected) and Speakers.

The digital output is selected however that does not mean HDMI digital. it is referring to the onboard S/PDIF port which is not used.

Anything else i can do to troubleshoot, or is it something needing to ship the board back for replacement?

Thanks,
Corey

Intel is the manufacturer for the HDMI driver. realtek has nothing to do with any of this. Realtek only controls the S/PDIF port and the analog audio ports. nothing else.

Check a few different screen resolutions. Is there no sound for any applications i.e. system sounds, WMP, DVD, etc?

Completely uninstall the Realtek HDMI drivers and re-install.

when i booted up this morning, i went to adjust my volume with my normal analog speakers. when i click the volume control, the default playback device was "Intel(TM) HDMI Device"

I went to play a song to see if it worked...no sound. Clicked back on the speaker and for whatever reason it reverted to Realtek Digital Output.

Any suggestions? it this a problem with the intel HDMI audio driver or the Realtek analog/SPDIF driver?

Thanks,
Corey

If you was playing the song in WMP, then you may want to check:
Tools - Devices - Speakers - Properties.

Also I am not sure if this is related but When I setup a Sapphire card to use the sound with a DVD I had to turn off Hardware Acceleration. Maybe WMP is the same if so;

Tools - Performance - Video Acceleration - Set to None. You may need to click the Advanced button (same Tab the none should do this for you) and uncheck both the Use Video mixing renderer

here is what my device manager looks like:

Realtek HD driver and intel HDMI driver are 2 separate devices.

im leaning towards a windows reformat. should i go that route? its not a problem if i do...i backup my data regularly so there is not an issue with doing that.

Thanks,
Corey
