Sound at 100% still too low.

I've got a refurbished Lenovo M95p and the sound is too low: either on the computer internal speaker or a pair of small external fed from the front earphone jack. The Lenovo site says that I have the latest drivers.
When playing small .wma files in AutoKey, the maximum sound is really low. Would playing .wav files be different?

Please update the specs on your computer in the "My Computer" section:

Check to see if you have a high definition audio CODEC installed.
If there is not one installed when viewing device manager have another look at the applications and drivers available on the Lenovo site for your computer's configuration.
View the available drivers for windows 10, windows 8.1 and windows 7.0.
Look for a high definition CODEC.
If you don't see one on the computer and there is one on the Lenovo website give the CODEC a try to see if it improves the sound.
