@@FiiOOfficialYes, that doesn't help. This can be replicated very easily. It happens every single time you press pause on music using Bluetooth or switch inputs. Open Spotify, connect to Bluetooth, play then pause. It pops every time you pause. I assume it has to do with the DAC not getting a playback signal when you pause. This none the less shouldn't be happening.
I have Windows 11 Pro, version 23H2, build 22631.3880. I encountered a problem updating the firmware in FiiO K19, however, I was later able to update the firmware from version M139 to version M146. I am sharing with you how I solved the problem. If for some reason the firmware on the FiiO K19 is not updated and you receive the message “Update failed”, following strictly the instructions, then try immediately disconnecting the USB cable from the computer after removing the FiiO K19 disk in Windows Explorer. I noticed that removing the FiiO K19 drive took a long time. After I ejected the FiiO K19 disk in Windows Explorer, then on the FiiO K19 screen the status "Waitting..." changed to "Updating..." and the FiiO K19 disk was still still in Windows Explorer and apparently , FiiO K19 could not access the “update.bin” file, and the waiting time of disconnecting the disk and reading the “update.bin” file of FiiO K19 is small, and as the waiting time expired, then FiiO K19 would throw an error about the unsuccessful update, namely "Update failed." If you follow the instructions and receive the message “Update failed”, then repeat, only after you remove the disk in Windows Explorer and the message on the screen changes from “Waitting...” to “Updating...”, then remove quickly connect the USB cable from the computer, the FiiO K19 disk should disappear in Windows Explorer, and wait for the “Update ok” message to appear. Now I have the firmware version MCU M146 DSP v0.9 FPGA v0.16
Hi, thanks for the kind feedback. But the engineer told me that the USB connection or not will not affect the upgrade. May be the issue you met was a probability bug.
Online Update from the Fiio app does not seem to work. It says no update available. I was able to update via USB no problem. This update still doesn't fix the popping that happens when switching inputs.
Hi, please try to force restart the M3K by holding the power button for 15s to see whether it helps? And try to update the firmware for you for help. If the issue remains, please contact support@fiio.com for help.
Hope the update fixes the annoying popping that happens every time audio stops while playing via any audio source.
Are there issues? :/
Hi, did you enable the smart idle option? If not, please try to enable it to see whether it helps?

@@RESURRECT2 Yes you can't swap inputs or pause Bluetooth without popping noises.
@@Aridgway only then ? I will use only one and no Bluetooth
I have the same issue with popping sound that happens every time audio stops :( Hope future firmware can fix this!
