Question

ı can hear the sound when ı choose the built in output.but ı dont hear when ı select studio 68c output

Answer 1

I don't have an answer, but I have the same problem with AudioBox USB 96.

Answer 2

Not sure if this is your problem, but if I have Notion open before plugging in headphones, it makes no sound with the headphones in. The solution to that is just exiting and opening it again (with the headphones still plugged in).
