Ubuntu – Laptop built-in speakers not working on an HP 625

hpsoundspeakers

After I did a fresh install of 11.10 but keeping my home folder which was used for 11.04, my laptop speakers didnt work anymore. Sound from analog headset still works, but would like to use my speakers also.

My laptop is the HP625 and the soundcard:
Card: HDA ATI SB(Radeon HD 4200)
Chip: IDT 92HD88B1

I have tried the following things:

  • Followed this answer and changed some kernel settings: Fast video playback with no sound
  • Unmute the speakers
  • ran the troubleshooting guide of ubuntu, which caused more trouble than it solved, all my sound stopped working and had to reinstall the kernel, so it would recognize my soundcard again

As a reference this is the aslascript, which may provide a linux/ubuntu guru more info than me: alsa information script

You can try following steps:

  1. First,open up a terminal window (Applications->Accessories->Terminal) and run this command:

    sudo head -1 /proc/asound/card0/codec#0
    

    it outputs your audio card type.

  2. Edit the configuration file by this command:

    sudo gedit /etc/modprobe.d/alsa-base.conf
    

    find out this section:

    > # Keep snd-pcsp from being loaded as first soundcard 
    > options snd-pcsp index=-2
    

    change it into:

    > # Keep snd-pcsp from being loaded as first soundcard
    > #options snd-pcsp index=-2
    > options snd-hda-intel model=laptop-eapd
    

Reboot,and the speaker should be working now
