de_paradox You can adjust the format of the Bluetooth receiver through the developer mode, the default is lhdc5.0, you can switch him to set to sbc, and then switch back to lhdc5.0, the problem of the murmur can be solved, the specific reason should be the system version of the software problem, I have also reflected to the team many times, but still did not wait for the next version of the update!
