Razer Kraken V3 Pro powered on yet off?

I’m using the Razer Kraken V3 Pro and Synapse 4 seems to be connected with my headset, however it says it is powered off. I press and hold the power button until the green light appears and flashes. This green light I’m assuming means that the headset is powered on. However Synapse still says the device is powered off, and I cannot hear audio. I’ve been stuck on this issue for weeks. (Also the dongle is plugged in securely)

 

I’ve updated the firmware, the pairing system, the drivers, I’ve uninstalled and reinstalled Synapse.

I’ve made sure all audio is on and the device is set to default. 

 

I would find it really helpful if I could see that green light turn to a red light which I assume means it is powered off.

Except despite holding the power button for much longer than necessary, I can’t seem to power off my headset. 

Yet at the same time, Synapse 4 thinks it is already powered off and can never seem to register it being on.

 

I’m open to any ideas, please let me know any suggestions or solutions. And if you guys are stumped, does anybody have a link to customer support with an actually employee? I’ve already gone through all of the videos and articles that Razer has to offer on my headset and audio issues. None of them have worked.

    Additionally, I now have audio, however Synapse 4 says my headset is currently powered off, despite it actively running and playing back audio.

      Found the cause (Kraken V4 Pro, Synapse 4 beta, wireless dongle)
      If Synapse starts before the headset has linked to the dongle (e.g. at PC boot), the headset module logs [init device data] battery status not available, do not continue. and never retries. Synapse then shows the headset as powered off with no profile/battery until the dongle is replugged, even though audio works fine.
      Check: search for that line in %LOCALAPPDATA%\Razer\RazerAppEngine\User Data\Logs\products_1383_mw*.log.
      Workaround: with the headset on, replug the dongle or fully exit and restart Synapse.
      Razer devs: the init path in the products/1383 middleware aborts when vl() returns false, instead of retrying. Retrying until the headset answers fixes it (tested locally).
