Sound coming out of the main headphone jack of my 192 mobile stopped working. I tested the headphones on another device and they are okay. I see the main meter running as if it's receiving signal, but I hear nothing. I re-installed Universal Control and my version of Studio One Professional and that did not help. I get no sound when using S1 or something basic like iTunes or Youtube. This is out of the blue - worked as expected last night.
