my work laptop has a problem where if no audio is being played on it for a while (on earphones) then the next time you start any audio for like two seconds it will play on the speakers before it switches to the earphones. i usually go around this by muting sound altogether, starting it, then after two seconds unmuting it. but uh sometimes i fucking forget and anyway this was like the fifth time in the past two weeks i managed to blast bts in the office at full volume.
