Question for Fiio M21 owners: crackling/popping issues

Hey!

I'm not here to start a flame, but I see some heat on this argument in this subreddit, so I wanted to ask the owners of the M21.

Do you notice popping or crackling on this DAP? If yes, when? On playback start, on track change?

Before looking for the M21 I was kind of decided on the Hiby R4 but reading about random reboots and other issues I gave up on it.
