Vista - Problem with System Sounds working intermittently

Sometime my system sounds work and most of the time they don't. My
Device Manager doesn't show any problems. When I right click on the
sound icon in the System Tray and click on Sounds, then try the sounds,
most of the time they don't work. I have all the latest digitally
signed drivers (HP Pavilion laptop). When I go straight to the Sounds
folder and try the sounds, they don't work. I don't even know which
app is supposed to play these sounds (it might help if I knew in order
to solve the problem). I have no viruses or malware in my system. Not
sure - but it seems like the system sounds stop working sometime while
the system is booted and has been running for a while. Please - could
someone offer some other things to check or try? What app is supposed
to run these sounds? Are there any other sites that might be able to
help (or other Newsgroups)? I depend heavily on these sounds working
properly so thi sissue is important to me to solve. If I've left out
any relative detail, please let me know. I need some help!!! Thank
you.........

Have you checked your plug going into the computer?
