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.

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

Thank you for giving the options that made it work.

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