I understand you are experiencing issues with your A50 + Base Station. Here are a few steps you can take to attempt to remedy the issues.
If using a gaming console (PS4/Xbox One) make sure the Base Station is in Console Mode. Power button should be illuminating Red. Check to make the switch on the side of the Base Station is switched to “Console”.
If using a PC or computer, make sure the Base Station is in PC Mode. Power button should be illuminating White. Check to make the switch on the side of the Base Station is switched to “PC”.
Try connecting the USB to different ports on the console and ensure the console is identifying the Base Station as your voice audio source.
Ensure that all the connections from the Base Station to the console or PC are secure.
