Here is the model of my laptop: http://www.gadgetsguru.com/hp-dv6-7040tx-lowest-price-spec-cheap-sale-india-15613.aspx

As the specs say, it has quad speakers with a sub-woofer... When i was using windows 8, i had no problems. But, now only two speakers work and no sub-woofer.

I recently switched over to ubuntu and i'm a newbie :).. Please post a step-by-step guide for installing audio driver.

I heard that alsa is pre installed in ubuntu 13.04

Thanks for your replies :)

You do not need installation but configuration. Please show the output of the alsa-info script. –  CL. May 25 '13 at 7:25

NO problem @CL. Got it working... Did the following:

First, edit the following file:

sudo gedit /etc/pulse/daemon.conf

Uncommment and change the values of these lines:

enable-lfe-remixing = yes
default-sample-channels = 4
default-channel-map = front-left,front-right,center,lfe

Second, edit the following file:

sudo gedit /etc/pulse/default.pa

Add the following line to the end:

load-module module-combine channels=4 channel_map=front-left,front-right,center,lfe
