I bought a HP ENVY 6-1060ss, it has 2 front speakers and a built-in subwoofer. I can't get the subwoofer to work. I have looked around for answers, and found quite a lot, but still, nothing works.

I have already tried (from already answered questions):

• Edited /etc/pulse/daemon.conf setting enable-lfe-remixing: from no to yes, and the channels number from 2 to 3.




• Edited /etc/modprobe.d/alsa-base.conf, adding options snd-hda-intel model=hp-zephyr and options snd-hda-intel model=ref.

Any other thoughts?
