We just switched our netgear router out with the Google Nest. Uninstalled Control 4 app & reinstalled. All is working fine except for speaker sound. I am able to pull up all of our music, select it and play it through the app, but there is no sound. There is also a solid red light behind the 4 on the control 4 black box. Waiting on dealer to call me back but they are awful about call backs. We have the OS2 system.
