Here's the thing guys. The studio one v4 was used by my crew was on windows. Everything was going on pretty well until the windows computer was dead, thus, we shifted our studio one v4 to a mac laptop. The main problem that could not be solved and could not be found by googling is that we could only turn the recording on. As you know, when you click the recording (which is the red button) on, the monitoring will be also turned on (which is the blue button). So here's the bizarre problem. If these two functions are all on, the sound of the tracks will be heavilly BUZZING! The BUZZING! However, if we turn off the blue one, the buzzing would be gone，which is really annoying. For now all the work that we need to accomplish is stucked. Could anybody help me solve this problem? Appreciate a lot!!
