Windows 7: Win 7 64-bit, ati 3650 hdmi - "not plugged in"

mitya · 19 Apr 2010

Hello!

After browsing through dozens of similar topics on the web, I'm beginning to get desperate, but I'm going to ask for a solution anyway.

My setup:

Windows 7 Ultimate 64 bit - clean install
Asus EAH3650 Silent graphics card with 2 DVI connectors (grey and yellow)
Samsung 226BW monitor connected via the grey DVI connector with DVI to DVI cable
LG LCD Full HD TV, connected via the yellow DVI connector, using the OFFICIAL yellow DVI-to-HDMI dongle that came with graphics card and HDMI to HDMI cable.

* Using this setup I had a perfect 1920x1080 picture on the TV with audio, when running Windows XP and TV connected as a second monitor, using extended desktop mode.

The problem:

No audio via the HDMI connection.
On Windows 7, the HDMI audio device status is always "Not plugged in". I cannot set it to be the default audio device, that option is grayed out.

Attempted solutions:

Installing the latest Windows 7 64 bit drivers for my card (with hdmi audio driver) from the ASUS website.
Installing the earliest available Windows 7 64 bit drivers for my card (with hdmi audio driver) from the ASUS website.
Installing the Realtek drivers for ATI HDMI audio device.
Installing the Microsoft HDMI audio drivers via Windows Update.
Disabling the onboard AC'97 audio

More info:

One thing that can be related to this problem is the fact that in Catalyst Control Center my TV connection is recognized as DTV (DVI) when, I suppose, it should be DTV (HDMI).
On the other hand, I don't think that the HDMI Audio device should have the "not plugged in" status, even if the HDMI cable is not connected.

I would appreciate any clue that will lead to a solution of this problem.

Thank you in advance!

Hey did you ever figure anything out about this? I am having the exact same problem and haven't figured out a thing to get past it.

HOLY CRAP! This might sound like crazy talk but just install the newest catalyst control, and buy the right dvi-to-hdmi adapter (has to be an ati adapter for the correct series video card) and plug it into the YELLOW DVI slot. Now my catalyst control says HDMI and I've got sound!

ok first of all when you hook up hdmi to a ati card you have a setting change that needs to be done in order for sound to go through the lcd

right click your audio disable main speakers enable hdmi there should be no problem the drivers should be there just need to change it

It is a manual switch especially if you are doing dual screen
