I have installed 12.04.3 in my HP DV6 7040tx. It has quad speakers + one sub woofer (Beats Audio). I went through many posts and i was not able to find the solution. I tried the package


But, i can hear only much of bass like voice and music.

Here are the configuration when i run lspci | grep "Audio"

    00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)

when i run cat /proc/asound/card0/codec#* |grep Codec

    Codec: IDT 92HD91BXX
    Codec: Intel PantherPoint HDMI

when i run aplay -l

Similar or the same?… – fossfreedom Sep 21 '13 at 10:00
Similar. I already went through that post. But, as i mentioned earlier, my sound has extra BASS which i can't control. The voice is not clear at all – dinesh2707 Sep 21 '13 at 15:06
Duplicate of this?… -- you should edit your question with all the posts and techniques you have tried. – fossfreedom Sep 21 '13 at 15:49
I created a post in spanish with the same problem ( i have a HP Envy M4). With this instructions i installed the HDA Jack Retask ( And there are instructions to put on the subwoofer (…) But, with this, my headphones doesnt work :( Good luck! – user278034 May 5 '14 at 1:22

I have a HP Envy dv7 with beats audio, probably similar sound hardware.

In Ubuntu 12.04 I got it working by doing gksudo gedit /etc/modprobe.d/alsa-base.conf and adding the line options snd-hda-intel model=ref at the bottom, then save the file and reboot.

Now under Ubuntu 14.04 this solution doesn't work anymore for me, but I found a solution on this thread in the Gentoo forums:

  • do gksudo gedit /etc/pulse/
  • add the line load-module module-combine channels=6 channel_map=front-left,front-right,rear-left,rear-right,front-center,lfe at the bottom
  • save the file, close all windows and reboot
  • open sound settings (through system settings or by clicking on the volume icon in unity and choosing "sound settings") and you'll have an extra configuration "simultaneaous sound output". Click on this, then test the sound using the "test sound" button to the right. For me 5 speakers out of 6 work now, only the subwoofer doesn't. Not perfect, but close.

Hope this helps...
