I have a KVM passthrough setup where both guest and host have their own sound cards. They are both connected to a logitech 5.1 X530 setup via a passive audio mixer I rigged up. This allows both systems to play audio to the same speakers.
At the moment I am having some issues with the audio mixer as some of the stereo jacks don’t make proper connection with all the bands on the female PCB connectors requiring some re-seating and wiggling to get proper connection. I used what was available locally at the time and it worked great for about a year. I am having issues with left and center channel connection on two separate PCB connectors and no amount of wiggling or re-seating is working anymore.
I am not too familiar with audio equipment and wanted to know if there is any mixer available online that would facilitate this task and not burst the pocket? I am also looking at buying proper components online and build it over properly.
A little ghetto looking but its got solid connections and is hidden away behind the PC:
