Question Weird crackling sound on some game

[Mrxyzl]

Hello, i notice that on some games ( like i play COTC) the audio output seem to crackling and distort, especially on speaker.
I check with dumpsys and the audio processing format seem to be force change to pcm_float instead of pcm_16 bit compare to others source (like youtube...)

here are the dumpsys for reference

compare to youtube
