Dolby Home Theater 4 Not Working on X1 Carbon Gen 3 Windows 8.1

2015-05-14, 14:20 PM

Neither the Spectrum Analyzer nor the Graphic Equalizer on Dolby HT 4 is working.  The dials on the graphic equalizer have not impact on the audio output. 

 

I've tried the directions provided here and here, but to no avail.

 

Any help or suggestions would be greatly appreciated.

 

Thanks,

Sid

Ah OK. I was testing on the laptop headphone jack (with a nice pair of headphones).

 

I do not have DIsplayLink installed.

 

Does Dolby work for you on the headphone jack?

Hi smansur, and welcome to the Lenovo User Community!


Why are you trying to make Dolby Home Theater 4 work on an X1 Carbon Gen 3 Windows 8.1?

 

The X1 Carbon Gen 3 comes with Dolby Digital Plus Home Theater, currently at version 7.6.3.1.

My intent was not to use Home Theater 4, but unfortunately my Dolby Digital Plus never worked. When I reviewed the forums, I followed the directions given in one of the other posts (referenced in my original problem description). That led me to use Home Theater 4. Unfortunately, that is not working either. For both Digital Plus and HT4, the problem looks like the audio is not going through Dolby and there is no response on the spectrum analyzer.

The hyperlink you posted points to version 6.0.1.7188 from March 2014. I already have a later driver installed (6.0.1.7383 from November 2014).

Thanks for the updated link - I installed it and the Dolby tool still isn't working.  I went to the Realtek site, and downloaded an even newer driver (released on May 11, 2015), and that also has not resolved the problem.

Hi smansur,

 

I have Dolby Digital Plus on an X1 Carbon Gen 3 here, as set up from the factory, and it's working. I have no idea what effect loading Dolby Home Theater 4 has.

 

Dolby Digital Plus is part of Lenovo Settings. You need the Lenovo Settings App from the Windows Store and the Lenovo Settings Dependency Package both installed.

 

Hope this helps!
