Need Help : Audio won't work when I attach my HDMI cable to my laptop

So yeah, I use a HDMI - HDMI cable to my laptop whenever I want to watch DVDs on it.
It used to be that the audio would work, but now that does not seem to be the case.

I've tried rolling back to previous versions but to no avail.

And yes, i've lurked through all the previous threads but to no avail.
The default audio device has been set to the TV's, the HDMI audio has been enabled and i've tried everything. Nothing

Please Windows 7 forum guys, you guys are my only hope!

Here are the specs

Acer ASPIRE 4741G
Intel Core 5-460M processor 2.53 GHZ
4 gig ram
Windows 7 64bit Home premium
NVIDIA GT 420M

found this info for you,give it a go and let us know how it went
- Click on the "Start" button
- Click on "Control Panel"
- With the Control Panel in "Control Panel Home" view please click on "Hardware and Sound"
- Where it says "Sound" in green letters there are three options below that are in blue click on "Manage Audio Devices"
- This will bring up a window labeled "Sound"
- On the "Playback" tab there is listed the sound options available to you. One should read "Digital Output Device (HDMI)" Click on that.
- There should now be a check mark on that option.
- The Sound should then play through your HDMI hookups to the TV.

Let me clarify things a bit.

- I want to watch some HD goodness on my TV
- I used to use a HDMI - HDMI cable for this and it worked
- Suddenly It does not
- Tried standard methods (checked to see if TV was default audio, HDMI enabled)
-Tried different cable, no luck
- don't have another HD tv to see if this an isolated problem
- TV is philips in case this matters
- I checked, I do have an HDMI audio driver. The built in one ( Realtec) and the video card (NVIDIA)

Any ideas now?

Have you checked your default settings under Hardware & Sound in the Control Panel?

Here is the image. As you can see, the Telly is selected as the default device.
No sound comes out. Even if the bar goes up and SAYS there is.
I checked the level and balance, and the TV is not muted. All should be well.

Have you checked the TV speaker settings on the TV itself?

There should be an option to choose between the TV's internal speakers or external speakers.
