Windows 7: tv to pc hdmi no sound

Windows 7 Professional 64 bit

You could try going to the screen mrdemon showed and then right click on any of the devices and select "show disabled devices" maybe then it will show up?

Have you tried disabling the HDMI sound in Device Manager?

Which video card does it have, and do you have the latest driver for it installed? Dell has downloads for all three of; AMD , Nvidia and Intel, most of which can't be considered recent. The audio driver for the HDMI on the video is included with the video card driver. With it being a desktop you should be able to get the appropriate driver directly from the manufacturer instead of what Dell has to offer.

Also when in the Windows audio properties make sure to right click and put a check nest to both disabled and disconnected devices, if you haven't already.

P.S. mrdemon you don't have the driver for your onboard sound installed, it is using the generic default Windows driver.

Windows 7 Home Pre

@ stormy13

i tried to install the Soundmax Drivers and it would Crash every time, Im happy with the sound the generic gives out as I only have 2 speakers and a headphone jack......

back to the POST.

The GFX card is
NVIDIA GeForce GT 220

Audio Input for HDMI SPDIF / HDA,

Try looking for SPDIF and activate it. Maybe the card does not like Pass-through.

The correct Nvidia driver installed?


which will also install the necessary audio driver for the cards built in audio. The GT 220 was one of the first Nvidia cards to have an audio chip on the card for HDMI audio, where the previous 8xxx/9xxx series used a SPDIF connection to the sound card and did do passthrough.

mrdemon, that link only deals with how to get HDMI audio to work with XBMC in Linux, won't help any in Windows.
