Sound Problems with Intel HDA on Ubuntu


If you are facing problems with sound when using headphones ex: the sound is audible on speakers and headphones at the same time, you can fix it by modifying /etc/modprobe.d/alsa-base.conf.

Determine the chipset using
sudo lshw -c sound
Determine your computer's model details
sudo dmidecode
Go to http://doc.ubuntu-fr.org/audio_intel_hda#acer and find the line you need to add

Take a backup of /etc/modprobe.d/alsa-base.conf and add that line.

Restart the system after you have saved the changes.
