Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

Recently, I decided to use Ubuntu as a work related OS. I was impressed with its overall performance and its simplicity (yes, Ubuntu is simple to me). Everything was working great until I found out that my sound card won't output any audio through the laptop speakers. If I use headphones, it works fine, but without them, no audio.

I am using an HP dv7 Quad Core edition (2013). I have configured the speakers, tried maximizing the volume settings, still with no speaker output.

All that it reads on the audio device selection panel is "Speakers; Built-in Audio"

My question is, is there a way to fix this issue? If not, when will it be available? Are there any drivers that should be available? For proprietary drivers (Additional Drivers tab), there aren't any drivers available, the list is just blank.

Here is a list of running devices if helpful.

I own a hp-dv7-7102ea which I believe is a very similar (but older) model so hopefully these instructions (which worked for me on linuxmint 15) should work.

how to make the speakers work

a system-wide equaliser if you still want to try and improve the sound even more :)

Also type "alsamixer" into the terminal to adjust the speaker and the subwoofer volumes.

Hope this helps! (Ps. read the comments on the FIRST link as they provide more detailed info which makes sure the headphone jack still works properly)

with thanks to CalcProgrammer1
