Do you have android 8.1.0? This feature is up to android version. If you don't have restricted custom ROM by seller it must work by setting in developer options. I'm sorry it's not working on your devices. I buyed the player from AliExpress and before ordered I asked seller if it supports USB audio and the answer was no, but when I tried it works.
What do you measure? I don't see the player to play something. Is in the background?

My quite old F.Audio S1 had some buttons got stuck, becoming unusable. I tried to open it to see if somehow can fix, after removing the back plate I noticed all buttons were working normally. When pushing the battery (gently!) the buttons stick again. It seem the battery swelled up a bit, maybe due to aging? (but battery life seems to be yet good) So I remounted the back plate without fully tightening the screws, and the S1 now works normally. It will still accompany me jogging
