Raspberry pi: no audio after update

I had a mini heart attack when I found that after the last update/upgrade of debian ‘Raspbian’ distro, audio was absent!!!
“here we go!” – I’ve said to myself – “Finally I’ve managed to broken this little pi..” . No audio, only music with HUGE noise! signal was so low!
But after a few minute I typed into a ssh session to the pi, the command “alsamixer” and found that audio was MUTED! Y U NO STAY UNMUTED AFTER UPDATE? everything is fine now.
Never get mini heart attacks for these things!

Snow Leopard, Audio, Volume, Headphones, Keyboard

Long story short. EDIT: found another person here ( http://forums.macrumors.com/showpost.php?p=13724101&postcount=3 ) with same problem.
When I put my Mac (with Snow Leopard) to sleep with the Stop command, the next time I wake up the system, the audio keys on my keyboard no longer work.
It’s a well known bug, that Apple still ignores.
At the moment I can only solve this problem logging me out and in again.
Checking in system preferences at the keyboard voice, is also good because there might be a checked box that say to use the function keys as , well, classical function keys in all computer in this world.
If so, uncheck it and everything works fine.
Silly bug. Could it be a problem with screensavers? I don’t know yet, but I will update this post if I find an elegant solution. And also please let me know if you solve this bug, I’ll send you a completely free bag of air from Sardinia (worth at least $1000)
