I understand you are experiencing issues with your A10 Standalone. Here are a few steps you can take to attempt to remedy the issues.
Make sure the inline cable is fully seated in the headset and on the Xbox One/PS4 controller.
Test out the headset by itself on an alternate device. You can either test it out on a PC or you can hook up the headset directly to any smartphone.
If these steps did not alleviate the issues you were experiencing, please go to the link below and submit a case. Let your agent know all the steps you tried and the outcome of your troubleshooting. It will help speed the resolution of your case!
