I can help you with the sound thing, but not so sure on the PDF files. To get your sound back download a driver for your speakers. This is probably the one. http://drivers.softpedia.com/get/SOUND-C...WHQL.shtml
If that doesn't work it might be a virus. You may actually have to restart your computer a couple times to see if it works. You may also want to check if your speakers are plugged into the computer.
If nothing works, try a virus scan. You can download AVG Free Edition right here. http://free.grisoft.com/freeweb.php/doc/2/
You can also try this. http://housecall.trendmicro.com/
If nothing works, just post up here and I'll try to help some more.
