Quite a few brands of laptop come with beats audio hardware these days. My actual model is a HP Envy 17″.
When I first installed Ubuntu 14.04 I noticed the sound was very tinny and just didnt sound right at all, then I figured out that the sound wasn’t actually coming out of all the speakers on the laptop.
The only solution that I have found so far is to retask the audio using “HDAJackRetask” which is part of the “alsa-tools-gui” package.
Fire up a terminal and install the package we need by doing -
sudo apt-get install alsa-tools-gui
Once installed head over to the dash and start typing HDA until you see the Icon for HDAJackRetask appear then run the application.
Once ran, select your codec and stick a tick in the box which says “Show Unconnected Pins” and just copy my configuration from the screen shot below.
Click Apply now to test, You should see that the sound is a lot better than before. Once you’re happy with it hit “Install Boot Override”
Hope this helps someone, if you know of any other way to get this working please comment I’d love to hear your solutions.
