Question Connect one chat headphone to 4 PCs

[Squiggles]

I need to connect one chat headset (speakers and mic) to 4 different PCs simultaneously so I can hear audio signal coming from either one of those PCs (with volume control) and use my mic to send signal to all of the PCs. I will need a mixer (software or hardware) that I can use to mute/unmute my mic signal on any PC.

Anyone have any suggestions? Best (potential) solution I found is the mixer linked below but it has terrible reviews. Is there a better way to do this? If I plug in 4 USB sound cards to a PC, is there a software i can use to achieve same results?

What is it you're trying to provide, like broadcasting a gaming session?

I don't know of a mixer that would simultaneously receive general inbound audio and output mic feed from you. I don't think multiple sound cards would work since windows can only handle one input or output device at a time. I suggest a quality stereo 4 input mixer to get your inbound audio and maybe use discord for your mic purposes instead.

I need to be on upto 4 meetings at the same time with ability to lower audio from either or all of them and speak on 1 meeting or all at the same time.

I found two diy solutions (active vs passive) that look promising.

Not sure about that stuff. Maybe be on the lines of conference meeting apps and such.

If you don't need to talk simultaneously on more than one meeting: simple four-channel mixer (where output from the four PCs is coming), and one 4-way switcher (where the microphone is going).
