Wifi working - now no sound!!

[debih]

Now the sound has disappeared from the little acer.

My sis said it ws working but now it isn't. It says there are no drivers installed.

Can I reinstall them?

Just seen this, I thought that it was part of the WiFi thread.

Yes, redo the sound drivers, it will not hurt, and check that you have not accidentally hit the Fn and F8 keys at the same time.... they mute sound.
