Core 1 - occasional digital-sounding crackle in left channel (mac os x)

Started noticing this recently. It's happening regardless of app (ableton, spotify, soundcloud) or output device (speakers, headphones). Anyone else having this problem?

  • Hi Ray,

    Thanks for posting. 

    First, what version of Mac OS X are you using? Have you tried using a different USB cable, port, or computer with your Core 1? Does this make a difference at all? When does the crackling sound occur?

  • Hi Bill,

    OS X 10.9.5. Have switched out cables and ports, but not computer. The problem only began recently, and it occurs randomly - i may go hours without hearing it, but then hear it repeatedly over a few minutes.

  • I would recommend testing on another computer, if possible, as this will help to narrow down if this is more of an issue with your Core 1 or the computer itself. If you don't have access to another computer to test this with, it's likely you'll need to service your product. Warranty and non-warranty claims are not handled here on the forum, but I can point you in the right direction! Here are a couple of options that you could choose from:

    • Submit a Warranty or Service inquiry with our Technical Support team by logging onto the Alesis Support Page. Select Warranty or Service Inquiry from the drop down menu.

    or

    • For quicker support, call your nearest Support Office or International Distributor.

    Make sure to reference or link this thread to help out the support team.

    I hope this helps! Let me know if you have any additional questions.
