The last Ubuntu upgrade included a kernel upgrade which messed with the wireless internet connection on my Samsung NC10 (see previous post).
What I did not notice straight away was that it also brought back one of the problems we have to deal with when first installing Ubuntu on the NC10, the speakers still working even when the headphone jack is plugged in.
I pasted into the terminal:
sudo apt-get install build-essential
This usually the first step to sorting the problem but it told me it was already up to date. So I then did the next step that I did on first installation. Download the latest Alsa [from http://www.alsa-project.org/main/index.php/Download] onto desktop. Right click on the archive and choose to extract to there.
Then paste in terminal:
./configure --with-cards=hda-intel --with-oss=yes --with-sequencer=yes
sudo make install
Lots of text will scroll by, pausing now and again to ask questions. You will be asked for your password, a “y” for yes and pressing enter if asked to ready for the next step.
Once it is completed set the volume of Alsa by putting “alsamixer” in the terminal then use the up key to set the volume to maximum. You only need to do this after installation then forget about it.
Restart the computer and go to the volume control applet in the top task bar, right-click and choose ‘Open Volume Control’. The mixer will appear. Slide the volume control up, as it is set to mute by default when it is installed. Done!
Now when I plug in the earphone jack the speakers on the front of the NC10 are disabled.
