muffle sound when Davinci resolve is opend.

This is the same issue with a reddit post but I can't post a URL here.

When the sound input device and output device is same, there will be muffle sound when the program is opened.
Not while in timeline, not audio scrubbing, when you are in project selecting there are already this annoying noise.
Can this be fixed?

Please indicate Resolve version, operating system, and computer spec (including GPU driver and Audio IO configuration).

Not reproducing this on the macOS and Windows systems here, so additional details would be useful.

Windows 11, DaVinci Resolve 19.1.4 B11, Bluetooth linked headphone (Bose QC).
This issue seem to be fixed when I use 3.5mm jack to link headphone and PC
