[OT] Two Computers, One Set of Speakers

[Peter]

You need a simple cable that is called a combiner. Someone could make it for
you. It contains 4 resistors. Lousy ascii schematic follows:

In1 L o-----R------*-----o Out L
                   |
In2 L o-----R------+

In1 R o-----R------*-----o Out R
                   |
In2 R o-----R------+

In1, In2 Gnd   o---------o Out Gnd 

All R are 32 Ohms, 0.25W fixed resistors. This assumes that the speakers are
amplified. A switch is not needed and you can listen to both (!!) sources at the
same time if you want to.

Caveat: The two computers and the speakers MUST use the same power strip and it
is better if you do not connect/disconnect them while power is on (especially if
using 3.5mm (aka 1/8") mini plugs).

Unfortunately I have no idea where one can buy such a cable. I have been making
my own (for up to 4 inputs!) for several years.

PS: You use this at your own risk. Ground faults and hot plugging *will*
eventually destroy your equipment if you are not careful.
