So the computer monitor I use has a passive headphone port in the back, with no other audio outputs.

It sounds great if I do use headphones but I would like to use stereo speakers if possible.

If I connect that audio port to my computer speakers which also plugs into an outlet for power, the sound comes out like bad noise.

Of course plugging the speakers to my computer works perfectly but I would also like to sometimes use the monitor for either my Xbox or Raspberry Pi.

Any help on this?
