No sound by speaker in ubuntu 12.04, only by headphones (re installing, updating and in liveUSB without sound)

Question

I installed Ubuntu 12.04 and the speakers don't work. Before I had 13.04 without problems about sounds.

I re install ubuntu 12.04 and update, and also no sound, only by headphones. Also I tried by Ubuntu Live and doesn't work.

I tried alsamixer, and the sound it's high. and looks like no problem all the configuration, but not are sound by speakers.

Solution

The solution provided here works for HDA Intel Soundcard. To find the make of your laptop soundcard click here.

Solution 1:

Try the following command in the terminal:

killall pulseaudio

Solution 2:

You need to edit this file /etc/modprobe.d/alsa-base.conf and then add a line in its end. Use the following commands:

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

Now add the following line at its end:

options snd-hda-intel model=generic

Now reboot your computer. It should solve your problem. If the solution doesn’t work then try the Further Troubleshoot.

no. that's doesn't work. :( Also in the source I tried editing /etc/modprobe.d/alsa-base.conf with options snd-hda-intel model=auto and not. It's strange that also in live cd and re installing ubuntu still not working.

I tried from a live USB of ubuntu 13.04 and also not sound. that's means that is confoguration of sound card maybe?
