Okay try this first:

After applying continue only if you are not satisfied. You may get some speaker popping as well as the loss of headphone support if you continue. Also consider that I am using a dv6t-7000.

Fist off we are going to be using a program called hda-jack-retask.
So to add that repository:

Code: Select all

sudo add-apt-repository ppa:diwic/hda

Then update the package cache and install the program:

Code: Select all

sudo apt-get update && sudo apt-get install hda-jack-retask

Now start the program:

Code: Select all

hda-jack-retask

'This is where it gets tricky. As this is for my laptop the following may need to be tweaked for other models.
Select the IDT 92HD91BXX codec (may be different on other models)

Check the "Show unconnected pins" box (the internal speakers do not show as connected)

Remap 0x0d (Internal Speaker, Front side) to "Internal speaker"

Remap 0x0f ("Not connected" but is the under-display speakers) to "Internal speaker" **On my system this breaks headphone support.**

Remap 0x10 ("Not connected" but is the subwoofer) to "Internal speaker (LFE)"

Apply now, then test with your favorite audio program (some may not work due to Pulse reset, so find one that does, verify sound is coming from all speakers).

If it works, select "Install boot override" to save the settings to apply at boot time.


Reboot. When it comes back, you should have full sound from all speakers. Also test headphones. Plugging in headphones should disable sound from all internal
speakers.

My sub-woofer is working great. I hope this helps someone.

Thanks..i'll try this.
BTW in 13.04 speakers atleast work(very less sound though) with the audio jack.
The above guide which i pasted enables 4 speakers and subwoofer but audio jack is of no use.
Thanks again.

I noticed that too. For some people this does not happen. I reset 0x0f and that fixed it. I don't think my system has that particular pair of speakers anyway. At least now my system is just as loud as in windows. And the sub works now.

Did not make much diff.. for me..!

Maybe you need to try the other pins. It could take time but you might find the subs pin. Also, look at alsamixer. To get the Sub to work best this is what my system looks like:

Notice the Loopback is disabled. If I turn it on the other speakers seem to be louder then the sub, therefore the sub is not noticed as much.

And maybe look at this:
Beats Audio Laptop question @ linuxforums.org

This is device i have :

What does hda-jack-retask say? It generally gives a better name for the Beats Audio card.
