I support 30 desktop computers for my company. I have a
new Dell one which has never played system sounds. It
will play CD's. I went all through the Troubleshooter
and checked EVERYTHING - Dell even came out and replaced
the motherboard. When you go into the Control Panel and
go to Sounds, you can't play any system sounds, the
little triangle is grey. (It is black and works on other
computers.) Any help?
