no sound via speakers in ubuntu.

hi! i just got ubuntu a few days ago, really liking it, except that there's no sound through laptop speakers... but there is sound through the headphone jack... any help?

my soundcard is whatever is in the m15x... thanks! =)

 

Usually, the speakers and headphone jack are fed by the same source, with a mechanical switch in the jack turning on the headphones and turning off the speakers. If that's the case with your system, the issue is with the hardware, not ubuntu. If it's not the case, ignore me.

Have you tried turning up the volume?

 

I don't think this is true in today's electronics. It's at least not true in my Asus laptops. Under Linux I can configure headphone jack sense off in the alsa driver, and get sound out of both the laptop speakers and the headphone jack at the same time. I think that the jack sensing is software controlled. You can read lots of headphone jack sense problems with alsa on the web, like this thread at the Ubuntu user forums.

Likely there is a problem with the OP's alsa driver version, or configuration. In order to diagnose the problem, more specific information is useful. There is this post over at Ubuntu forums for a user setting up alsa with an Alienware m15x, and the OP might have better luck inquiring there.

Good Luck..

 

when i try to save that file in ur linke "post" it says i don't have the rights to or wahtever, how do i loginto root to save it? or how do i open the file via terminal, since i kno how to log into root there..

 

1. Open a terminal window (you don't have to be root)
2. Open the file with gedit with this command:

Code:

sudo gedit /etc/modprobe.d/alsa-base

3. Add the following line to the end of the file:

Code:

options snd-hda-intel model=mbp3

4. Then save the file (You have to close gedit to return to your active terminal session)
5. Close the terminal session
6. Reboot the computer

Good Luck..
