No HDMI Output device in Windows 7 for ATI Radeon 4650

Hi,
I recently bought a ATI Radeon 4650 graphics card. It has an HDMI output on the card. I have connected this directly to my HD television, and whilst I'm getting great video output, I cannot get any audio out.

I'm running Windows 7 32-bit and I have installed the Catalyst 9.11 drivers (the latest as far as I can see).

I've read many forum posts that talk about a HDMI Output device that gets listed in the Sound Device options in Windows. Unfortunately I cannot get it to appear. There are no devices in Device Manager that require drivers.

My motherboard has an on-board Realteak High Definition Sound Card which is enabled in the BIOS and is working on Windows. However, I want to get sound out of the HDMI cable.

I know this is possible but I'm falling at the first hurdle.

Can anyone offer any advice or suggestions as to how to get this to work or why this might not be working?

Thanks,
Sam

Well, I'm not sure why you are not getting the HDMI output device to not show on the Sound devices. That is where mine sits. There is one thing that you can try:

In the sound devices page, there should be the item "Speakers" possibly along with some other devices. Right click somewhere in the sound devices box, and it should have an option to "Show Disabled Devices". If you check that box, it should show your HDMI output, which you can then enable.

Hi,

I switched the video card to a different machine and it worked immediately! I think there is something about my other PC's motherboard which wasn't compatible. It will remain a mystery for the time being - thanks for posting replies though.

I have a gateway SX2800 with the ATI radeon 4650 and all was working great until I upgraded from vista to windows 7. Now, I cannot get sound through the HDMI. I have the lates drivers. I'm able to enable/disable the ATI Realtek HDMI output, but there is no sound. I spent hours messing with this. Any ideas

Shuggill,

Have you gone into Sound in Control Panel and selected the default playback device?

Also, Microsoft does have an official Windows 7 Support Forum located here http://tinyurl.com/9fhdl5 . It is supported by product specialists as well as engineers and support teams. You may want to also check the threads available there for additional assistance and feedback.

HW conflict between 2 realtek sound-chip in your PC.

There is a potential conflict between the 2 sound chip on your setup... The 1st is a realtek sound chip on the motherboard. The 2nd is another realtek sound chip on the ATI Radeon 4650.

Try to disable the on-board sound card from BIOS.

After boot up go to control panel sound-option and make sure your playback is set to "ATI-HDMI-Output"

That should assign the output to the HDMI port going to your TV.

I fixed mine !
I went to http://www.realtek.com.tw/downloads/ and Under High Definition Audio Codecs, I downloaded ATI HDMI Audio Device R2.35 then under ATI HDMI Audio in the device manager, the words "Not Plugged in" disappeared. NOW THE SOUND WORKS. I don't really understand why this worked, because I had all the latest drivers and the correct items listed in the device manager.

tried all above..still no sound thru HDMI.. and the High definition sound unit is marked with conflict (Code 12) ..no other device shows conflict.. so guess its the MOBO (AGP] cihpset driver that really is the problem/dont play well with my card.. :pt1cable:  :pt1cable:

Does anyone have a solution for this?

Many thanks!

Hi.

I'm equally frustrated by this issue.

I recently upgrated my HTPC with a new Motherboard and processor. I installed a Gigabyte H55M-UD2H and the Intel i3 Dual core chip. This rendered my HDMI connection useless.

I now have stunning video signal through the HDMI cable but no audio whatsoever. I get great audio through my S/PDIF cable and even through the mini jack output, but i desperately need the combined signal.

I'm running a legal Retail Windows 7 Home Premium 32 bit. In my device manager there is a yellow conflict symbol. I think this may be the cause of my problem. It shows 2 High definition Audio drivers present - one is working correctly, the other is saying (Unit cannot start (Code 10) ... I seem to remember my old configuration showing a HDMI device in the Device manager, but my new mobo seem to have forgotten about this ...

I've tried downloading several drivers on Realteks website - even the one called 'ATI HDMI Audio Device R.42' which had me cheering because i was quite sure i had struck gold on this one - but no ... The driver rolls back in the middle of the install, saying "This driverpackage does not include a supported driver" - still no HDMI Device present in my Device Manager.

I even tried disabling the Azalia Codec in my BIOS which seems to carry the onboard Audio. This just caused the two High Definition Audio items in my Device Manager to disappear. After re-enabling tha Azalia Codec, the items returned whith the same conflict.

I've tried all suggestions in this thread and I'm getting quite frustrated and i'm running out of suggestions on this issue and could really use some expert guidance. Please help me.

Thanx in advance

I share your frustration, because sometimes I get sound thru hdmi, sometimes not.
I tried for a while enabling an disabling different playback devices (ATI HDMI, PC speakers headphones) but I did not succeed in getting sound thru hdmi.

Now I am getting it but I do not know for sure why.

Perhaps I do because I switched something in the "Display / Connect to a projector" back and forth among "projector only / duplicate etc" but I would not bet on it ...
It is worth a try , however

I had a very similar problem and after spending hours on this found a solution - some video cards seem to (by default) assume resolutions that certain screens cannot sustain. My case - my sony bravia hdtv (waned to use as a media center) was assumed, by an nvidia card, to work with like the ONLY resolution it couldn't support.

The solution is simple:
Connect the display to the computer using the connection type you want to use (hdi, dvi, vga etc). Power on. hit F8 a bunch of times and you get the windows boot up choice screen thing. Select boot with limited resolution (640x480) i think, let windows start up. Right click on the screen and go to the screen resolution settings, start adjusting. Make sure you click "apply" and not "ok" with every change because if you selected a non-functioning resolution, your screen will go dark for about 15 seconds but will revert to its previous setting after the 15 secs are out. Find the settings that look / work best and dont worry about what Windows is suggesting in terms of "best resolution".

In respects to the sounds - both DVI and HDMI normally have both audio and video support. That said, if you use a DVI - to HDMI converter, the sound will often be neglected.

Hope this helps.

Thomas,

I have the same motherboard with an Intel i3 Processor. You need to install Intel MEI driver from the CD that came with your motherboard.
