Title:
"Dummy output" -- No sound in Ubuntu 12.04. Worked in 10.10
Status in “pulseaudio” package in Ubuntu:
Incomplete
Bug description:
"Dummy output" is the name of my card. It obviously doesn't work.
I was finally able to fix the issue (temporarily), but trying these
solutions I found online.
(0) updated first
$ sudo apt-get update; sudo apt-get upgrade
# rebooted
(1) Didn't work
$ sudo apt-get remove --purge alsa-base
$ sudo apt-get remove --purge pulseaudio
$ sudo apt-get install alsa-base
$ sudo apt-get install pulseaudio
$ sudo alsa force-reload
(2) PPC fix? I have some custom built PC, not PPC, but I thought I'd try it
$ gksu gedit /etc/modules
# added:
# snd_aoa_i2sbus
# snd_aoa_fabric_layout
# snd_aoa_codec_tas
# snd_aoa_codec_onyx
(3)
$ sudo killall pulseaudio; rm -r ~/.pulse*
# rebooted
(4)
$ aplay -l **

(5)
$ gksu gedit /etc/modprobe.d/alsa-base.conf
# added:
# options snd-hda-intel model=auto
# options snd-hda-intel model=hp-dv5
# options snd_hda_intel model=hp-dv5
# rebooted
(6)
$ alsamixer
cannot load mixer controls: Invalid argument
(7)
$ pulseaudio -k
(8)
$ sudo alsa force-reload

(9) here are my devices
$ aplay -l **

So I think added the lines to /etc/modprobe.d/alsa-base.conf helped?
