Hibernate - > OFF Then Speaker POP using AMP-CTRL

**mbkowns** · 10-04-2005, 04:55 AM

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

What is amp-ctrl?

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
