[linux-laptop] ACPI and sound on un-hibernate

[PTSD]

When I take my laptop out of hibernate, there is no sound available.
Asus A2500H
Mandrake 10.1 official.
Everything else restores nicely. USB video, etc.
I am fairly new to linux, so please be gentle. 
Any help is greatly appreciated.

Sorry, I am new and if I made a mistake it is not that I didn´t try.  The site  
http://mobilix.org/howtos.html is dead so I could not read the howto.
