Volume Control of My Soundbar/AVR is Slow or Fails

Check Control Center's settings of your soundbar/AVR by going to Settings> Devices> [soundbar/AVR name]. 

CEC
If the current control type is listed as "CEC", make sure the soundbar/AVR has CEC enabled (check that device's manual or search online for instructions).  If that setting is enabled but unreliable, you may want to try switching control type to IP (only supported on some AVRs) or IR by selecting Settings > Devices > [AVR/Soundbar]> Test Control

  • During Test Control, the control "type" will be displayed onscreen (IR, CEC, IP).  If you have previously tested a control type and it worked, you may wish to answer "NO" (even if it is working) to test the next available control type.

IP
If the control type is IP, make sure your soundbar/AVR is connected to your network.  If you are using a wired connection, check the Ethernet cable to make sure it is plugged in snugly. As a last resort, you may wish to restart the soundbar/AVR, your router, and Control Center in case there is a network issue.

IR
If the control type is IR (infrared), try enabling CEC control on your soundbar/AVR, if that is an option, and going through Test Control again. Otherwise, Control Center will require a direct "line of sight" with an IR transmitter to work properly. If the "line of sight" is changed/blocked, or the transmitter is moved out of alignment, IR control can become sporadic or stop working altogether. If the device, or Control Center, is behind a closed cabinet door you will need to point an IR emitter at the device in order to send a signal.

  • Make sure Control Center has a line-of-sight to device. If you are using an IR emitter, check its connection to the IR port on the back of Control Center.
  • Check that the transmitter wasn't bumped out of alignment. The transmitter should point at the sensor (IR window) of the device you intend to control.
  • Try restarting the soundbar/AVR and Control Center
  • Make sure the device being controlled has the latest firmware. Many soundbars/AVRs are not always connected to the internet to receive updates.

IR can be difficult to troubleshoot because it cannot be seen with the naked eye.  Try using a digital camera (your phone's front-facing camera will likely work) to "see" the Infrared signal blasting from the Control Center box as well as any attached emitters. Control Center has two emitters on the front and one on each side that will light up when issuing IR commands like Volume UP/Down.  This is also a good method to determine if your IR transmitter is actually sending a signal or not.
