No Audio via HDMI to TV

[Imran5]

Hello all,

Okay, so I have seen this thread posted a few times but after trying out all of the methods posted with no luck I thought it was time for me to ask for some help.

The problem:

Sound is working fine through my laptop speakers but when I connect it to the TV via HDMI cable the sound still comes through the laptop.

I was previously running Windows Vista Home Premium and it worked absolutely fine. As in, the sound came out of the television speakers when I connected the notebook to the TV. I recently upgraded to Windows 7 Home Premium and since then it does not work. I would appreciate if anyone could help me.

Right now the default sound output device is: Speakers/Headphones - SigmaTel High Definition Audio CODEC. The other two listed are Realtek Digital Output (Optical) - Realtek High Definition Audio and Digital Output Device (HDMI) - SigmaTel High Definition Audio CODEC.

When I try either of the other two sound does not work at all. With the Realtek one it seems to recognize the sound but I don't hear it anywhere and with the HDMI one, it doesn't work at all i.e. Fails to play test tone. I have installed all the latest drivers according to manufacturers.

Thanks in advance,

Imran

I don't know if this might help as well. Thanks. =)

 

[Imran5]

I tried to update the latest NVIDIA driver using the modified inf but I still had no luck with the sound. Also installed the latest REALTEK drivers. Can anybody help?? It would be greatly appreciated.

Hi Imran5, I presume you did select xxxxxxxxx(HDMI) as the default device whilst the cable was connected?

 

[Imran5]

Yep. Tried all three in fact! To no avail! :-(

Thanks for the reply

 

[amzo]

Try Forceware 195.39 Win 7 | Vista (64-bit ) download from Guru3D.com if your on a 64bit OS

 

[Imran5]

I'm on 32bit.. So I'll have a go at that one instead! Thanks =)

 

[amzo]

Ok...Best of luck...

 

[Imran5]

An epic fail! lol.. I'm close to calling it quits

Thanks for the help though!!

 

[amzo]

Thats ok....have you the latest Audio drivers installed for windows 7 too?...if not try that...Also in Device Manager is all ok with the devices?

 

[silentloner]

I am having this issue with my Sony Vaio VGN AR71ZU I cannot select my hdmi port to get it to be default

 

[Imran5]

Yep I've got all the latest drivers installed and everything is fine in Device Manager! I cannot fathom what's wrong.. I might just whip out my old 2.1 Logitech speakers and plug them in lol, instead of relying on my TV sound haha..

im having the same problem with my pc (gforce 8600m GT) everything is installed with the latest win7 drivers, I have HDMI video output, but when I choose HDMI sound output. I don't hear anything. The test sounds don't work.

I don't know what it might be..

have you found a solution yet?

 

[Imran5]

Nope.. Sadly I haven't.. Looks like a common problem though!.. I'm not alone!!

 

[eSKa]

I've solved it using an older vista driver I found on the acer website (installed it using comptability modus) now it I have HDMI sound too
you can find the driver on the acer website--> go to notebooks/aspire/5920g/vista ultimate 64

I'm having the same problem on a Sony VGN-FZ31M with GeForce 8400M GT. "Digital Audio (HDMI)" is listed in Playback Devices but as "Not Plugged In" even though it obviously is.
I've been using Logitech speakers as a workaround too.

A solution has been found. Read this:
