No sound on Ubuntu 12.04 after upgrading from 11.10

I have recently upgraded my Ubuntu 11.10 distribution to Ubuntu 12.04 LTS on my HP pavillion dv6 laptop.

This is the output from 'aplay -l' command of my system.

card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: STAC92xx Digital [STAC92xx Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

After rebooting I noticed that I had no sound. After trying many things, to resolve this problem I had to add the following two lines to the "alsa-base.conf" file.

alias snd-card-0 snd-hda-intel
options snd-hda-intel model=auto

If this does not work then replace "auto" with the following keywords one at a time. Save the file and restart your computer each time you test with one configuration.

ref                    - Reference board
mic-ref            -Reference board with power management for ports
dell-s14           -Dell laptop
hp                     -HP laptops with (inverted) mute-LED
hp-dv7-4000  -HP dv-7 4000
auto                  - BIOS setup (default)

Reference :- ubuntu 12.04 no sound vostro 3300 i5


  1. thankyou !

    I used model=auto (model=hp did not work on my dv7)

    On a HP Pavillion DV7-2014TX the external speakers dont turn off when pluggin in headphones

    1. I do not think this issue is related to the issue you are having. Sorry.

  2. Hello

    I had the same issue on a hp pavilion dv7 2238sf.
    Thank you for giving the options that made it work.

    alias snd-card-0 snd-hda-intel
    options snd-hda-intel model=auto



  3. Many thanks. After spending way too much effort trying to get my audio to work again, this solved it.

  4. You are awesome...... this worked for me

  5. # Ubuntu #62691, enable MPU for snd-cmipci
    options snd-cmipci mpu_port=0x330 fm_port=0x388
    # Keep snd-pcsp from being loaded as first soundcard
    options snd-pcsp index=-2
    # Keep snd-usb-audio from beeing loaded as first soundcard
    options snd-usb-audio index=-2

    so how do i add the next code? as put above?
