lenovo n500 no sound on hdmi win 7 sp1

Hi ,

I tried to follow other threads with similar problems with no success.

I am running lenovo N500  4233 and recently upgraded the OS to WIN7-32bit  SP1. I was on vista previously.

Since the upgrade I lost the sound on the HDMI output and could not reconnect since.

The problem only occurs on my philips 42PFL HDTV. I tried it on sony and it works.

I have tried numerous drivers with no help.

 

computer profile:

LENOVO

Chipset :GM45

Bios version: 6GET18WW(V1.09)

Geforce 9300M GS

Driver Ver.: 8.17.12.6099, 10-16-2010 (tried alot of them)

 

On lenovo toolbox it says

Sound Card:  NVIDIA High Definiton AUdio

Driver ver. : 1.1.9.0

Sound Card:  Conexant High Definiton ...221

Driver ver. : 4.55.0.0

 

The NVIDIA HDMI Output always appears as "not plugged in" and I found no way to change this. this is not a HW problem, it worked perfectly in Vista and works on Sony HDTV.

 

 

Please assist in fixing the sound issue,

Tamir

Hi,

The link leads to a poor solution of downgrading WIN7 to Vista.

This was not what I was wishing for.

There has to be something I can do.

Please help.

Tamir.

Re: lenovo n500 no sound on hdmi win 7 sp1

sound failed after win7 upgrade,

sp1 did not help with this issue.

so no sound since win7.

Uninstall current nVidia driver and try this one.

Re: lenovo n500 no sound on hdmi win 7 sp1

did you un-install current drivers before upgrading vista to 7?

Re: lenovo n500 no sound on hdmi win 7 sp1

Hi,

I have unInstalled current version of nvidia and reinstalled 267.76 you recomended.

the NVIDIA HDMI Output remains "not plugged in".

 

how can you explain that sound works on other TV brands? what does the driver look for in order to validate the existance of a sound device?

 should I downgrade to vista?

where can i find the recovery discs? are they online somewhere?

 

Regards,

Tamir.

Re: lenovo n500 no sound on hdmi win 7 sp1

have you tried to upgrade tv's firmware?

if you have more hdmi input on your tv, try to use another one.

As yigit said, try to update your current TV firmware.

 

This is a common problem between nVidia and Philips.
