I use an analog 3.5mm Y splitter from my HDTV and PC to my Logitech

right speaker's volume is lowered from my PC's audio.

I may just buy a switch. I should clean up my desk and make more room.

I also have a KVM switch that is buried on the desk, since the 2nd big
computer failed. I'll dig that out.

I was going to suggest a switch.

One caveat: be careful to not operate the switch while there is sound.
Some output circuits heavily dislike this and burn. I learned this the
costly way.


We bought a powerful amplifier, nominally for home use, but hey, you can
not put 250 watts in the sitting room and survive it. So we used it for
a small cinema-club theatre. We didn't have money to buy a professional
sound system.

We also bought a switch box that allowed us to switch on/off pairs of
speakers in the room, to adjust to the amount of people, while
maintaining the impedance.

Well, it worked for a while, then an internal fuse blew. We repaired it
on warranty, but they warned us that we were not "home use". Well, 150
watts is 150 watts, no, who cares where it is used? They told us to turn
the volume full down when operating the switches.
