[B] External Microphones will not detected by the drivers

What does happen?
By using a splitter adapter at the audio jack, no external microphone will be found.
Detailed description with pictures could be found here:

As you mentioned in the other thread this is likely due to the splitter/adapter not having the appropriate connections.

I’ve also seen some adapters and cables that have three bands but only one or two actual connections inside (cheap Chinese products usually), so they look like they should work, but just don’t. If the mic and speakers work fine when directly plugged into the V there’s nothing wrong with the port.
