For those out there who have low volume on their speaker, there are two way to increase it without any special software.

#1 Click on volume then click on speakers. Then go to enhancements. Then check the box "Loudness Equalization"

#2 For additional and really loud increase:
#1 Click on volume then click on speakers. Then go to enhancements. Then check the box "Equalizer" Then create your own custom equalizer setting by raising the 3 equalizer buttons and give it a name of your own.

I can't post the URL, but there is a Youtube video on this.
