C540 Touch sound problem

I have been researching, trying to figure out why my sound on my Lenova C540 Touch is not as loud as it used to be. I have the sound all the way up, but it's nowhere near as loud as it was when I first got the computer.

 

I think it might be because of the whole Windows 8.1/Dolby Advanced Audio problem I've read about in other posts. I confirmed that my Dolby Advanced Audio is not working.

 

However, none of the online solutions apply to me because they mention different drivers than what I have on this system. I don't have Convexant. When I click on the properties, details, of my speakers, it says Audio Endpoint. When I go to driver details, it says "no driver files are required or have been loaded for this device."

 

I tried to unistall/reinstall Dolby Advanced Audio, but that didn't do anything. Dolby still doesn't work.

 

Just for information, this is what is listed under audio inputs and outputs: microphone (lenova USB audio), speakers (RealTek High Definition Audio), Stereo Mix (RealTek High Definition Audio).

 

Please tell me what I can do to get Dolby running again and whether this will make my sound loud again.

 

Thanks in advance for any help.

Re: C540 Touch sound problem

hi jpschaper,

 

Welcome to Lenovo Community Forums!

 

Open Device Manager and Uninstall the audio Driver under Sound and gaming controllers,

    make sure to place a check under delete driver software prompt.

 

Open Control Panel Uninstall a program and uninstall all Dolby Related component.

 

Open Drive C: and Delete the folder says Driver or drivers

 

Install this driver

 Realtek Audio Driver V6832  

 

 

After installation open C: Driver/s

You should find the Audio driver folder and a dolby gui or pcee4 will be in ther and an installer of DolbyAA or advanced audio

 

Hope this helps

Cheers!

Re: C540 Touch sound problem

Sorry I didn't get around to trying your solution until now.

 

It didn't work. I followed all of the directions. Dolby Advanced Audio still doesn't work and the volume level was not affected.

 

Should I have installed the other application that was included in the driver file--Dolby Home Theater--instead?

 

Do I need to run DolbySelectorTaskPatch.exe?
