Beats audio on HP envy dv7, Ubuntu 14.04.1

Problem: Only two speakers working on HP Envy dv7 7390eb laptop with Beats Audio
System: Ubuntu 14.04.1 fresh install
  • Everything I tried relating to changes in /etc/modprobe.d/alsa-base.conf, like adding the line options snd-hda-intel model=ref or variations on this, did not work
  • Following this thread I did
    gksudo gedit /etc/pulse/default.pa
    and added the line
    load-module module-combine channels=6 channel_map=front-left,front-right,rear-left,rear-right,front-center,lfe
  • reboot
  • Click on volume control icon (top right of Unity) and choose Sound Settings (or click on the gear icon -> system settings -> Sound, which brings you to the same)
  • In the tab "Output' an entry "Simultaneaous output to Built-in Analog Stereo" has appeared. Click on this, then click on the "Test Sound" button to the right. In my case 6 speakers appear: front-left, front-center, front-right, rear-left, rear-right and subwoofer. Testing them 5 out of 6 work, only the subwoofer remains silent. Which is acceptable for me, for the time being, and a big step forward from only two speakers...
