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.

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
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

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?
