New [21.1.20 Mi 9] Can't Detect Earphone

[raaaaaald]

It usually can detect my usb-c earphones. And I can't exactly determine what causes the problem. The most recent case has been while I was playing a game with my earphones on and I turned on battery saver. From that point onwards, the game played its audio through the phone's speaker. Tried removing and reconnecting my usb-c earphones but all audio is still playing on the speaker.

Tried to reboot both game and phone and I still can't get it to work. First time I experienced this, a simple reboot did the job.
