[gentoo-user] Plasma sound devices

[Peter Humphrey]

Hello list,

Over the last few days I've trimmed my plasma setup - to slightly below the 
minimum, by which I mean that sound notification has stopped working. I can 
hear streamed radio, but the plasma control panel doesn't show any devices so 
I don't hear notifications.

I've scanned the list of packages I removed but I can't see a likely suspect, 
and google just returns results about having no sound at all, which is not my 
case.

Can anyone tell me which plasma module I need to install to hear notifications 
again?

Again, the hardware and low-level drivers are fine: it's just plasma that's 
missing a component.

Peter.
