Comment 70 for bug 25896

OS: Kubuntu / Ubuntu Hardy Heron
Hardware: Core2 Duo T7300, Intel Santa Rosa, i965 graphics chipset
Laptop: Littlebit Sepia X35 (Asus Z37E)

I have the same problem on Hardy Heron, sound does not work after hibernate / suspend. However, I can make it work manually by applying following procedures after a hibernate/suspend session:

1) kill all audio/video applications (e.g. killall kaffeine etc), including the volume applet (e.g. killall kmix)
2) then unloading and reloading the sound module
modprobe -r snd_hda_intel
modprobe snd_hda_intel
3) restarting the audio/video applictions (e.g. kaffeine) and volume applet (e.g. kmix)

Alternatively, the following command works as well:
sudo /sbin/alsa force-reload
However, it kills all audio/video applications, including the volume applet, which have to be restarted manually.
