If you're experiencing any difficulties with the sound in Serato, please close the software and check your computer's sound settings to make sure that your Input and Output are set to the default devices.  If either is set to your controller, it will cause a conflict with Serato's audio settings.

• Windows: Input should be set to "Microphone Array" and Output should be set to "Speakers (Realtek Audio)"
  
  
• MacOS: Input should be set to "Built-In Microphone" and Output should be set to "Built-In Speakers"
  

Once these are set properly, you can reopen Serato and try again.  If using external speakers, open the Serato settings, navigate to the Audio tab, and confirm Use Laptop Speakers is NOT enabled. Use Laptop Speakers should only be enabled when you do not have external speakers to connect to.
