UNIX for Advanced & Expert Users

Nowadays I run Mandriva, Ubuntu and Fedora Core. All of the operating systems works fine on my computers. GRUB gives me the opportunity to select an operating system.
I have Windows too. I don't run Windows. I like UNIX.

Today I work with 3 computers with a single monitor. This is possible thanks to the KVM switch.

I have a single HP printer connected all the 3 computers. I bought a separate switch and it works fine.

I want to connect my stereo to all the 3 computers.

I need your help for finding a switch for this end.

Nowadays I just remove the cable and connect to the particular computer which I want to listen to music, video etc.

I am tired of removing the cable comes from the stereo unit to one of the computers.

I beg your help to find solution/switch for this purpose.

Two options for this, you can mix the audio output together(google 'phono mix') or just switch it(google 'phono switch').

I don't know about google 'phono mix' or google 'phono swtch'.

Where are they? Do I have to buy them?

Please tell me more about this.

Those are instructions not devices.

Corona meant got to google and do a search for "phono switch" and "phono mix".

You could also search for "audio source switch".

Probably Radio Shack, or any stereo shop, would be a better place to ask.
