Hello,
I have a problem with my Norton 360 Premium running on Windows 11 (Surface Book 2) and Sony WH1000XM4 headset. Basically when Norton 360 is installed I am getting sound output issue very often. When you listen to music it just stops and you need to go to the sound output settings and switch to the laptop speakers and back to the headset. Also when you on the meeting and you can't clearly understand if a person stopped speaking or you faced that sound output issue. It's really annoying. I could reproduce the problem using same headset and another Surface Laptop 3 device (has Norton 360 premium installed as well). I can't reproduce that issue on another laptop HP EliteBook running Windows 10 with the same headset (Norton is not installed). I also tried to uninstall Norton 360 from my Surface Book 2 and issue has gone. I've tested during a couple of days and the issue didn't appear. Then I installed Norton 360 again and lost sound output in several minutes. Issue appears multiple times per hour. I tried to uninstall Norton again and the issue disappeared. Tried to install Bit******** security suit just in case, no issue there. I had several conversation with technical support agents, but there were unable to fix the problem by adding headset's mac address to a trusted list of devices or by setting my network as trusted or by temporary disable a/v protection and firewall.
This needs to be fixed.
