Hey. I have also uppdated the MCU for volume drop fix, but i was met with another problem. After the update i no longer have volume drop, but outright audio driver crash from time to time which is way more annoying. I'm on windows 10 pro and am currently waiting for the email response for the mcu downgrade file. I tried uninstalling the driver and reinstalling, but it happened again today. For the record i'm on 5.30 version of the fiio driver instead of latest 5.50, because of another audio bug that happens with the latest driver and basic windows driver which installs by default. The bug is that it cuts initial audio of notifications when there is no audio playing. It's like it's late to wake up and cuts off initial audio. Easily testable with windows audio test in windows audio device panel. I haven't tried the latest driver, because i don't want to settle for the bugged driver. I really hope i didn't somehow break the device while updating the MCU, so i hope that i can fix it by going back to the old MCU which had volume drop. I can handle the volume drop it wasn't that annoying, but audio crash is really a dealbreaker. For now i tried downgrading the mcu to the older volume drop fix version K7_mcu_firmware_v1.0.66 which
@radman uploaded earlier.
@FiiO Did anyone else report the audio crashing from time to time after updating MCU or is it just me?
