What ho one and all,

My wife uses an HP Pavilion 23 ''All In One'' computer. She like listening to various famous pianists and watching the associated videos. Recently the sound has become very 'rattly.'

I have removed the back and checked for anything loose, taped a few things that did rattle when tapped, gently blew some air into the speaker box but to no avail.

Any ideas on what else I could check? Or doe it indicate that the speakers have given up the ghost?

Thanks and toodle pip
