I'm running the android version of the Z64 I've been using the A2 air mouse. Sound usually routed through a Sony mini system via Bluetooth. Recently I noticed it in Netflix. The sound takes up to 15 seconds to start after the video had already been playing. The volume takes equally as long to change after its been adjusted. If it changes at all. I noticed it does it with more apps now too. I tried Uninstalling and re-installing apps to begin with. Problem still persisted. Did a factory reset on the Z64 and problem seems to have gotten worse. Anyone have this issue before or know any ideas to try?
