I just received my HP Envy 15 (June 2012 model) and I cannot get my audio system to fully function.
This laptop has 6 speakers.
1.) 2 speakers on the front of the laptop (Stereo). 2.) 2 speakers above the keyboard, just before the LCD hinges. 3.) 2 Subwoofer speakers underneath the battery cover facing downward.
Only the 2 speakers in the front are working.
This is a "Beats" audio system. There have been many beats audio laptops before this one, so maybe if someone has experience with those, it might translate to this device.
