Make Acer Extensa headphone speakers Work on Ubuntu

March 21, 2008 |

If you have purchase a Acer Extensa 4620, 5620, 4620Z and have Ubuntu installed. You may encounter one problem: mic/headphone jack/speakers don’t work out of the box. To get audio working, you may need to tweak your system a bit, follow the steps below, and you will work it out!

1. install install linux-backports-modules-generic by running the following command in the terminal

sudo apt-get install linux-backports-modules-generic

2. open audio configuration file by first running the command below in the terminal
sudo gedit /etc/modprobe.d/alsa-base

3. now you may see a chuck of code similar to the one below:

options snd-via82xx-modem index=-2 options snd-usb-audio index=-2 options snd-usb-usx2y index=-2 options snd-usb-caiaq index=-2 ...

add the following line of code at the end of the chunk of code:

options snd-hda-intel model=acer

4. double click speaker icon to launch volume control. Make sure under File > Change Device > HDA Intel is selected. After that select “Edit” “Preferences” Then check every device listed. When you close that you should now have Playback, Recording and Options listed in the Volume Control. In Options select “Front Mic”. At this point I could record audio from the Sound Recorder with the built in mic but it was way too loud and distorted so play with the recording levels until it sounds good.

By now, you should have your mic/headphone jack/speakers, everything internal external working!
