Intel 82801G Headphone and Sound Issue

I came across another issue on my Compaq Presario C500 laptop with regards to the audio. An issue exists with the Intel 82801G (ICH7 family) High Definition Audio (HDA) audio controller with regards to the headphones. When plugging in the headphones the sound continues to come out of the laptop speakers. There is a simple and quick fix to this issue:

Resolution

Edit the /etc/modprobe.d/alsa-base f/etc/modprobe.d/alsa-base file:

sudo gedit /etc/modprobe/alsa-base

At the end of /etc/modprobe.d/alsa-base add the following:

options snd-hda-intel model=laptop

Reboot the system and the headphones should work as expected.

System Used

  • Compaq Presario C500 laptop
  • Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
