To begin with, I am using Audacity 2.1.3. along with an Audiobox USB (which interfaces with my desktop), a TEC TC-753LC Phono Preamp with volume control, Technics Direct Drive Turntable SL-D2.
Here’s the problem: my Imac desktop died on me so, I transferred the audacity software and the previously mentioned hardware to my MacBook Pro - but, when I click on the “Monitor” Icon like I have done countless times with my desktop, nothing happens. I see the Audio level bars moving, but I no longer hear anything through the speakers of my laptop.
Now, I also transferred the Presonus Universal Control Software/App that was also formerly on my desktop - but, still no joy.
You transferred the Audacity application to the new machine but not the preferences. To hear what you’re recording, click on the Transport menu and choose Transport Options > Software Playthrough (make sure it is checked).
That sounds like you have the internal microphone set as your recording device and you’re getting feedback.
Remember, you lost all your settings when you moved to the laptop.
In Device Toolbar, set the recording device to your USB interface.
In Transport > Transport Options make sure Overdub is off.
Now try to start monitoring.
