Manjaro Bug - Audio devices disconnecting after plugging out the AC adapter when system is about to sleep

Hello there. I have a bug report: The audio devices are disconnecting after plugging out the AC adapter when system is about to sleep. If you let the system sleep, then plug the AC adapter out, everything will be alright. I am using Kernel 5.11.2-1. I don’t think this happens in the latest LTS kernel though, but I am not sure. Thanks!
