    Hibernate - > OFF Then Speaker POP using AMP-CTRL

    I use the AMP-CTRL service to start my two amps. Works great no more speaker pop when I turn on the computer ever. When I hibernate now though it shows the screen hibernating and then when it cuts power it pops and powers off.

    Is there something I can do for this? I did search but most people have the power on speaker pop vs the hibernate power off pop.


    Let me know thanks

    It has NOTHING to do with ground loop isolator.
    You should look into via anti-thump technology

    Okay. When you shutdown the machine, all services/apps will be shutdown and the PC power down. That mean amp-ctrl cuts power to the amps before the PC cuts its power. Thus, no pop.
    Now with hibernation, none of the services/apps are shutting down. The amps still have power before the PC shutdown. Thus, there will be a pop.
    Now, you know how to work around
