How To: Acer Extensa sound output problem

Postby Zen Mod on Tue Apr 15, 2008 4:08 pm

Problem: internal speakers work, external speakers/headphones do not, jack being plugged in should mute internal speakers, it does not.

Solution:
Open Terminal and type (you need a working internet connection to do this):
Code: Select all
sudo aptitude install linux-backports-modules-generic
sudo gedit /etc/modprobe.d/alsa-base


Enter the following line at the bottom:
Code: Select all
options snd-hda-intel model=acer

SAVE and close terminal, restart the system, the issue should not be present after restart. Tried in Daryna and in Ubuntu on Acer Extensa 5220, also received a confirmation that the same helped on extensa 5620 with the same initial problem.

This might work on other laptops if you switch "model=acer" to the appropriate model

I noticed that this problem reappeared on several forums, always involving Acer laptops, solved it and hopefully other Acer laptop users might find it useful. Can't tell if Dell or HP, MSI, Asus, Toshiba, Sony etc, laptop users have the same problem.
