Comment 17 for bug 222428

Sorry for my bad english.
This worked for me (also with playing amarok):

sudo gedit /etc/default/acpi-support
adding soundcore module to MODULES="" section like this:
MODULES="soundcore"

this remove and reload after suspend all sound modules (maybe a bug of a snd* module).
my soundcard is a realtek ALC861VD with snd-hda-intel module
I have downloaded and compiled HDA driver from productor's site.
I use ubuntu 8.04.1 on fujitsu siemens amilo li 1718.

also worked the previous:
sudo /etc/init.d/alsa-utils stop
sudo alsa force-reload
sudo /etc/init.d/alsa-utils start
