Windows 7 HDMI Sound Output Problem!

Hey guys!

Turned on my laptop yesterday (connected to a 32' TV via HDMI), usually gives me sound out of the TV but randomly stopped working!

Here is what i've done:

1. Switched to a different tv (same problem)
2. Changed HDMI Cable (same problem)
3. Uninstalled audio driver, intel (high definition audio device) and reinstalled.
4. Tried to enable the HDMI in control panel under "Sound", there is no option only the standard driver (see pictures)
5. Also right clicked and checked "Show Disabled and Disconnected "
6. Uninstalled graphics driver ATI Mobility Radeon HD 5650 and Reinstalled.
7. Tried to install a realtek driver.. didnt work

Computer specs:

Product Name: HP Pavilion Dv6-3034tx

Operating System: Windows 7 Ultimate 64-bit

Processor: Intel i5 @ 2.27GHz.

Memory: 6GB Ram

Graphics 1: Intel HD Graphics (p.s. couldn't uninstall, black screen)

Graphics 2: ATI Mobility Radeon HD 5650

Iv'e tried most things and i am out of ideas.

The sound will not come out of the TV but will come out of the Laptop.. I have uploaded a few pictures below to help!

Thanks guys!

That Laptop uses the IDT HD Audio Driver


If that isn't the one you installed try it.

Configure the default audio playback device:
Right-click the Speakers icon in the notification area at the far right of the taskbar.

Click Playback devices.

On the Playback tab, click either Digital Output or Digital Output Device (HDMI).

Click Set Default.

e. Click OK.

You should have 2 "High Definition" audio devices in Device manager and audio playback devices. The on-board audio chip (which you have) and the ATI Radeon HDMI chip

From device manager, view devices by connection and browse to the video card section - will probably show up under a PCI bridge connection, then "scan for hardware changes" and see if it picks up the Video HDMI chip under the same bridge.

Seems picky sometimes when you install the AMD Catalyst whether it will pick up and install a driver for the audio or not.

It's in the settings. Open the volume control while you have the home plugged in,click on sounds and change it (it should have 2 options on there)
