I wasn't sure what section to post this in... so here it is, sorry if it's in the wrong place.

On our laptop (Acer Aspire 8930G) I can't seem to get sound through HDMI since formatting it!

It was on Windows 7 x64, but due to the OS getting slow and buggy I formatted, installing the same OS back onto it. Since then, the above fault has occurred ^^

Video is working on the TV, but when I look into the playback options, the HDMI lead is listed as 'unplugged'.

I've tried installing the most up to date sound drivers direct from the Realtek website, alongside the most up to date GFX drivers from the Nvidia site. Also tried removing all these, and re-installing the drivers from the Acer website, but this hasn't worked.

If anyone can point me in the right direction, or offer some tips/suggestions that would be great. I'm completely out of ideas, and I have no idea how it was working before and not now.

Btw, as the HDMI port is technically a sound and video port, what controls it? would it be a sound driver or a video driver fault most likely? Or do the drivers work along side each other?

Click Start, go to control panel, go to where it says Hardware and Sound and click on the actual words "Hardware and Sound", then the third option down is "Sound". Right underneath "Sound" it says "Manage Audio Devices". Click on that and then click on where it says "Digital Output Device (HDMI)" When that highlights, go to the bottom and click "Set Default" then click "OK"
 
I get this problem too.

I've got my TV hooked up to my PC via HDMI and have to do the same procedure Lemin has described every time I want to watch a film through my PC on my TV. Usually involves me having to unplug my 5.1 from the back of the PC as well.

I'm sure there must be another way to configure it, but its not much hassle really.
 
He won't be able to set it to "default device" because in his screenshot it's greyed out indicating it's disconnected.

Are you trying to set it to the default when you connect the HDMI cable upto the tv. All your drivers are fine, otherwise it wouldn't show up there in the first place.

This. I can't set it as default cause it's greyed out 'not plugged in'.

Yeah, I'm trying to set as default while it's connected up. Tried un-plugging and plugging theHDMI cable in, multiple restarts with and without the HDMI cable in while restarting, no success :(

It's an HDMI audio driver that you are after, it's normally bundled with the graphics drivers. I've always had ATI, so no experience with doing this on Nvidia. However, have you made sure to select custom install when doing the graphics drivers, as the HDMI audio driver may just not be ticked as default, as it's sort of seen as an optional extra.

What's your device manager like, no yellow rings or nothing missing?

Sounds a right pain in the .... Simple but impossible, always the worst problems. Let us know how you get on. Has Google brought anything up?
 
When I installed the latest nvidia driver direct from the nvidia site, I did do the custom install and install the sound driver as well. This hasn't worked though.

I'm not sure if I had the Realtek audio drivers installed at the same time as having the nvidia audio drivers installed though. I'll have to re-do this step making sure the realtek drivers are gone.

There is one object in device manager which is not installed. It's listed as an unknown object, with no information, and windows update can't find anything for it. It's probably the finger print scanner or bluetooth device though, as I don't use these or have them installed.

There's a few people after searching google with the same fault I have, but none of the websites/forums have a solution that resolves it.

I'll have a play about with it for a few more hours when I'm off *sigh - technology*

If anyone wants to chuck in an idea, it wouldn't go a miss :)

Ty guys <3
 
I'm all out of idea's I'm afraid. I'll keep an eye on the thread, hopefully you get it sorted.

One last wee thought. When you did a reinstall, did you use a Windows 7 disc? Didn't the laptop come with a recovery partition? Did you delete this partition when formatting. I was thinking if you did a recovery using that partition it would have all the drivers on it pre-installed.
 
Silly question, but has your tv more than 1 hdmi slot & is it set to the correct channel when trying for sound. Clutching at straws here.
 
On my TV I have to use the highest numbered HDMI port. I also have to make sure to have the TV selected to view that port prior to booting Windows.
 
Right - I'm off, and going to have a play with this to try and fix it!

Just checking on thread before I get testing.

I did use a Windows 7 disc Buch, and yeah - I formatted the recovery partition.
TV seems fine, every other HDMI device works fine on it.

I'm gonna take the Realtek sound drivers off the laptop now, and see what happens with just the nVidia drivers on, then try with just Realtek and the default GFX drivers which Windows uses. See what happens >.>
 
Right - It's fixed. That didn't take long.

I'm sure I tried this before, but what fixed it was uninstalling the nVidia HD Audio drivers, and keeping the Realtek audio drivers.

When I tried that previously, I must have been using an old nVidia, or Realtek driver.

Only thing is now, when I close the lid on the laptop, it nocks the audio off and I have to restart the laptop to get sound through HDMI again. Plugging the cable in/out doesn't bring it back to life. All power options are set to 'do nothing' when the lid closes aswell. Pretty sure I can fix that by setting the TV to be another desktop though.

Well at least it's sorted now! Thanks guys for your inputs :)
