Hello sorry to bother you, but I tried to find the answer in the presonus frequent problems, but I can't find my answer.
I recorded in garageband, I can hear it through headphones only when I plug in through mac headphones plugin, I can hear the music playback
But I can't hear my voice in the headphones when I want to record a new track.
If I connect the headphones in the audiobox, I can hear my voice in through the headphones but not the music that is already recorded in garageband.
I use: iMac - OS sierra version 10.12.5
mic samson condenser
