Hi !
The Audio Adapter PCBdisplays a warning about NEVER connecting VGND and GND.
But does it apply to line-out pins ?
(I'm currently creating an Teensy-based audio guestbook with old phones and the wires between the main element of the phone and the handset contains only 3 cables, so if I want to avoid replacing the wire by a 4-cable one, it should be useful to be able to share grounds).
If it is a bad idea to share grounds between line-out and MIC, please tell me.
If it generates bad record quality, you can tell me too
Thanks
