HP DV7 Beats Audio alsa.base Modification. What should be the line?

My laptop has 2 front speakers + 2 next to screen + 1 subwoofer.

• If I don't edit alsa.base I get 2 speakers under LCD.
• If I put this in alsa.base, i get: $ options snd-hda-intel model=ref

I do get sound from 2 front speakers + subwoofer, but don't get the sound from speakers under LCD.

• If I put: $ options snd-hda-intel model=hp

I get 2 + 2 speakers "muffled" but not the subwoofer. Anyone could help?

I am also on the DV7 model with beats audio. I used following line (like you did):

 options snd-hda-intel model=ref

After that ofcourse you reboot, but then you should go to your sound preferences. There you can choose for either "Analog output" or "Analog headphones" on the output tab. This trick worked for me to enable all 5 speakers.

There are 2 downsides though. If you plug in headphones, some speakers will keep playing, and the sound quality is absolutely not like it is when playing under Windows.

If you would discover a better solution, please keep me posted!
