ffmpeg + sox transcoding and gapless playback

Are you using flac:wav24 (transcoding using MinimStreamer only) or are you using some other transcoding setting that does transcoding using ffmpeg and libsoxr? If it is the latter, try the former to see if that helps.

You could also try converting the album to wav24 using an offline converter such as dBpoweramp. Do you still get the problem?

If the problem is related to a slightly longer delay, the only solution will be a change to the renderer to handle this correctly.

So, I spent some time testing this out; whether I use ffmpeg or MinmStreamer's internal transcoding for FLAC, I still hear the slightest 'tick' between tracks.

I've since moved my library off of the NAS share onto a Thunderbolt drive directly connected to the Mac Mini running MinimServer, so the storage is as optimized as I can make it (it's fast).

There isn't any delay ... it's just that little tick, which is annoying with Volumio. So, for now I will go back to just native FLAC.

EDIT: also, I tested this with and without BubbleUPnPServer in the mix - same result with two different renderers (Volumio with upmpdci and Bryston BDP-1 with gmediarender-resurrect).
