Hello everyone. I have a HP laptop model dv1677ea that I run fc6 on with no problems except for one thing; when I suspend the machine (suspend2) to disk and resume I would have no sound.

Things would run ok without complaints it's just that I hear nothing. Some people on the net suggested unloading and reloading the sound drivers but that didn't work because the snd-hda-intel module refuses to unload as it claims to be in use. lsmod shows that snd-hda-intel is in fact in use by one thing but it doesn't say what it is. does this sound like something that was built into the kernel is using the module? if so what could it be? (when I compiled the kernel have configured everything in the sound subcatigories as modules). any hint?

Before you unload the module you must stop the service.

Can you post your /etc/hibernate/common.conf ?

Change there:
"Restart services"
alsasound (or equivalent in FC)

Also there is a :
Suspend2-users mailing list
Suspend2-users@lists.suspend2.net
http://lists.suspend2.net/mailman/li...suspend2-users

Thanks biophysics. I actually couldn't find alsasound or any service related to sound in chkconfig. Is there any other way alsa could be restarted?

can you post output of:
$> ls /etc/init.d/

/etc/init.d doesn't have alsasound or anything related to sound. So after some googling I found out that FC6 (and some say FC5 too) does not ship with alsasound script anymore. So just this morning I grabbed the file alsasound from a fc4 machine and placed it in /etc/init.d and did chkconfig --add alsasound and all went fine. Now the hibernate script takes care of restoring sound through
RestartServices alsasound

in /etc/hibernate/common.conf. Thanks biophysics for pointing out the alsasound stuff. The problem is solved now and I'm much happier
