Comment 26 for bug 274424

I have an HP dv3-2155mx and am having no sound in Ubuntu 9.04. So far all the suggestions I've tried have not worked for me. I can't even get the sound to skip/echo/repeat. I changed the playback and tested all available options in the System-> Preferences-> Sound. I installed PulseAudio Volume controller and verified the graphic meters were moving when the sound was playing from Totem Movie Player. There are no start up and shutdown sounds. I've read on some forums that the kernel needs to be recompiled with certain options switched on (irqpoll?) but says the side effects of irqpoll is that other devices are "delayed" (touch pad,etc). Any help would be appreciated!

I tried adding this to my /etc/modprobe.d/alsa-base.conf: (I tried "sudo alsa reload" and rebooting my machine)

options snd-hda-intel model=hp-dv3
options snd-hda-intel enable_msi=1
options snd-hda-intel single_cmd=1

also tried adding:

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=hp-dv3
options snd-hda-intel enable_msi=1
options snd-hda-intel single_cmd=1

*** I changed the "model=" to "hp-dv5" & "3stack-dig"
