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

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

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