Playing Dark Side of the Moon via Qobuz however, I don't experience this issue, it plays gaplessly, it's just 16/44.1 FLAC files over DLNA from JRiver it seems.

I have tried running the Pro on the supplied power adapter and with a large USB 5V power bank, same thing whatever combination I try.

I also experience a crackle sound at the start of some songs, it's not loud but it's very noticeable, especially on headphones, again on both Coax and S/PDIF. I get quite a gap between songs, in particular I just played Dark Side of the Moon and there was over a 4 second gap between Time and The Great Gig in the Sky. WiiM Pro in a second room connected to a Rega DAC (tested over both Coax and S/PDIF) and hard wired to the network, with WiFi turned off in the settings and fixed volume output selected. Nothing else runs on this server, just JRiver sharing FLAC files over the network via DLNA. JRiver27 on a dedicated music server running on Linux Debian11 and set to act as a Music Server. Initial thoughts were very impressed indeed, but after some listening I came across a problem I thought wasn't an issue, gapless playback? Hopefully there is a solution I've missed, as I really like the player and don't want to return it, but this is a deal breaker for me. My first post here after taking delivery of a WiiM Pro today.
