No HDMI audio out with Windows 7

vaio7 · May 7, 2009

After upgraded from Vista to Windows 7 RC, there is no HDMI audio out from my HDTV any longer. It can display video, but just no sound. In Playback Devices, it show HDMI Output as "Not Plugged In". I got Sony Vaio Realtek audio card and Nvidia video card. My audio driver is up-to-date with Win 7, but why there is no sound??? Any suggestion?

thanks

Go to control panel, choose to view either large or small icons (near top right), then click sound. Have a look there and/or post a screenshot.

Do you plug your tv into the video card out HDMI? Could be a video card driver issue.

thanks for the response. I'll post the screen shot once i get home

This is the screen shot while hdmi cable is connected.

I'm not very familiar as you could probably tell with using HDMI, but possibly your motherboard has a port for this and also a video card?

...and the cable is actually connected to a completely different HDMI port than what is showing here?

Probably not, but it's a thought that came to mind. Can't see why else it would say that it isn't connected when it is. Would have to be driver issue if not.

Do you use two HDMI wires, one for the audio and one for the video, then where do both HDMI's connect on the TV?
Or is there a cable that goes in between the audio out and video out, where you can connect a single HDMI wire?

I personally use HDMI for video and coaxial/analog 5.1 for audio..

I found that right clicking on the HDMI output and setting it as default device, that the audio now works on the HDMI. The only issue I have is that when I want to listen to the sound through my PC speakers, I have to reset Speaker/HP as default. Hope this helps.

I'm having this exact same problem. I have an ATI 4850 on an ECS motherboard. Sometimes I have both audio and video just fine over hdmi, and then other times I have only video and the audio panel shows the same "not plugged in" message. Once that happens the only way I have found so far to fix it is to uninstall and reinstall the ati driver. It is quite annoying.

I have same problem. Before install Windows 7 it had not happened but in W7 7100RC and 7229 yep.

I can't do anything for resolve this, and i'm going crazy :S

PS: I have the LATEST drivers for nvidia geforce 9300M GS (186.03) and I did tested many others

i think i figured it out ...conect to the tv..and switch to projecter only(press the windows key and P) .go to playback devices and then click on your default speakers..while they ARE THE default DEVICE and then click set as default communication device...then set the hdmi as default device..hat did the trick.. now it automatcailly switches audio.

I am getting the same issue. I have a Dell studio 1737 with windows 7 64-bit and when I connect hdmi from comp to tv, only video no sound. Inside playback devices there is no option for hdmi device, only speakers/headphones (which is default) and independent (r.t.c.) headphones. No hdmi choice there. However, when I go into device mangaer and open sound, video, and game controllers section, Intel(r) high definition audio hdmi is listed there. I have uninstalled and reinstalled that device, all drivers and windows updates and everything is up to date. How do I get that option listed into playback devices? I have been searching everywhere and gone through Dell tech support and thus far no results, somebody please help.

Byoung1447 · Nov 1, 2009

Ok, after trying everything I could think of with my Dell I finally got sound through the hdmi. Here's how. When I right click the
desktop and then the category display options and then output to and chose digital television the video goes through the hdmi just fine no sound though. No choice for hdmi in sound playback devices. However, if I go
to display options output to and choose extender and then digitial tv + notebook the video is now on my tv and notebook. And now in sound playback devices I have the option for hdmi audio device and I set as default and it works flawlessly. My new question is how can I get the picture and sound to come from the tv while the notebook screen is dark. It's not a big deal as is, but would be nice. Hope this helps somebody out there.

Hi everyone HDMI Sound Problem Solved,

After installing the new windows 7, the hdmi icon on the playback devices menu disappeared.

Here is what i did and got the icon back and make the hdmi sound work again.

The intel graphic cards needs to be updated. The link below will take you to intel site and it will detect the required updates for your system.

Intel® Driver Update Utility

Run the program and install the required updates and restart windows. HDMI icon will be back and the sound will work normal like it used to.

I hope this will solve everyones problem with the hdmi sound issue. I have hp Pavilion dv6, i m happy to hear the crisp clear sound from my Philips Hts6100 sound bar.

i downloaded the updates but still no hdmi icon in playback devices???? Although the ' audio driver for Intel desktop board' could not be identified.. would that still cause a problem??

reghakr · Nov 29, 2009

For you guys that haven't updated your computer specs, that would help a great deal.

Hdmi fixed

Hi all,
had the same problems as above. Have an Asus p5n-d with onboard realtek hd audio. Everything was fine in win7 32 bit but got no sound via hdmi with win7 64.
After much playing around solution for me anyway:
right click Realtek Digital Output icon on taskbar (the little speaker icon)
select "sounds"
on my pc the sound windows shows options for "speakers" or "realtek digital output"
highlight "realtek digital output" and at the bottom of the window click the "set default" option this got it working for me

good luck

Vinno

Great, after downloading the intel driver, i now have lost the picture on the input tv screen. It is fine on the laptop but bearly readable on the tv, really white..... The only plus is i now have the sound for the hdmi. I have since downloaded the graphics driver from dell, and it said that it was an older version than the one installed (the intel site one), hoping it would fix the tv problem but didn't.. this is really frustrating as i'm and too good with computers.
does anyone have any ideas????
