Windows 7: Loss of monitor sound via HDMI

Cassar · 22 Dec 2012

Sometime over the past 3 days i have lost the sound come through the Sync-Master SB550_s27B550v (HMDI) i am at a loss on how to restore the sound.
In the sound setting there is no monitor displayed only Speakers (front headphone jack works). & Realtek Digital Output.
in the Realtek setting i have mute the rear output device, when a front headphone plugged in.
i have also tried to run the sound of the monitor via the front jack and this wont even play sound through the monitor.
I can add any more details, and thanks for any help

Cheers Cassar

You should have HDMI listed as a Sound Playback device. Whatever happend apparently removed or disabled that.

To start, go the the Souind Playback panel and RIGHT click in an empty spot in the panel and then LEFT click to show disabled and disconnected devices. If it now shows up you can set it as default and you should get sound back.

However, if its missing, reinstall your video display drivers and that should get it back.

The HDMI audio is part of your video card, NOT the RealTek audio.

The ATI HDMI Audio not plugged in is the source of the problem. The Video is not detecting the plugged in HDMI cable. If you have done it, unplug then plug back in the HDMI cable and see if that helps.

tried using DVI to HDMI cable no sound
also connected monitor sound via line out line in still no sound
uninstalled monitor re installed still no sound
there is still no TV display in the sound options

There is no audio on the DVI signal, thus converting that to HDMI will not provide HDMI audio.

Do you have a System Restore point back to a date BEFORE all this happened and it was working correctly? If you do try the System Restore and see if that corrects it.

Click on the Start orb and enter System Restore in the search box. It will be listed in the results.
