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!
