Disconnecting the PCLink
After the recording session is complete it is recommended that you disconnect the USB cable from the PCLink. This process is necessary for audio to once again be played through your computer speakers. Once the PCLink is disconnected from the computer, Windows will automatically reassign your soundcard as the preferred audio device.
With MacOS, the PCLink is automatically selected as the preferred device when you connect it via USB. When disconnecting, you simply pull the plug out of your Macintosh computer and it will return to its original configuration.
