I have a DR-05X that has a strange issue. When I first power it on and press play for the first time it will absolutely deafen you with a split second of sound at maximum volume and drops to normal. After that I can press play all day long but I won't get the blast again until I power it off and on again. It has done this since I got it new in March 2019, but I never got around to deal with it. I just updated the firmware hoping that would solve the issue but no luck. Any ideas?
