Hi there,
I have made a small device using a 4PDT switch, 2 3.5mm TRRS jacks for outputs and 1 3.5mm TRRS jack for input (from headset). Switching between my laptop and my pc.
It does the job great but I am unable to understand why doing this, the microphone isn't picked up by my mac?
When I connect the device, my mac goes from "internal speaker" to "headphones" indicating it has detected a device plugged in to the port, and indeed, audio works perfectly. The same isn't true for the input section, which when plugging the headset in directly, goes from "internal microphone" to "external microphone" - this doesn't happen.
Would anyone be able to shed some light on why this wouldn't be picked up, just because the signal is going via a switch? I've checked the continuity of the microphone signal and can't see any issues there!
Many thanks
