What I have and a map of the speakers:
The Model: HP Envy 15 3040nr
What this does not show is that there are actually 4 speakers in the front so in summary there are 6.1 speakers:
- two on the front left
- two on the front right
- two above the keyboard
- a sub on the bottom the laptop
Audio only comes out of the front, and I'm not sure if it's all four or two of the four.
I can't figure out what to do software wise, being a complete noob to Ubuntu/linux, but I got that Alsa thing if anybody wants to take a crack at it.
