Did you mean "turning my A30p off" or "turning my A30p on"?  Or did you 
mean "I hear strange hard-disk noises when suspending-to-disk"?  Yeah, 
I know, you're posting from .de so English isn't your first language, 
but details can make a lot of difference.

If you meant "Sound works when I first turn the machine on, but after I 
suspend-to-disk, sound stops working", then the thing to do is to rmmod 
all the sound modules before you suspend-to-disk and have your APM 
script modprobe all the sound modules on resume.  The APM daemon's 
configuration file should be in /etc/apm/apmd_proxy or /etc/apmd_proxy, 
but your distro may have put it in a nonstandard place.  Check the man 
pages for apmd and apmd_proxy to find out where it is.

If it ain't broke, fix it until it *is* broke.

The hard disk on my A22p has made similar noises (usually a 
"clack-clack-clack-clack-clack" every few hours) for as long as I've 
owned the machine.  I run smartctl -a on the disk every week and I 
haven't ever seen any problems reported.  I'd trust the IDE SMART data 
over "feel" here, but you can do what you want.  HTH,
