Gapless (groan) with RoPieee and BubbleUpnp

[dartmoor]

The gapless thing refuses to go away :-( but first let me say this:

Whoever thought of and designed MinimServer needs a sainthood,a knighthood, a MBE and whatever else is going... it's a godsend!!!

OK.. I spent years using Clunky Twonky on a WD NAS - and then quite by chance I found minim - proper tagging for classical music - clearly somebody actually gives a shit about a minority interest and thank god they do. Thus far I've not played around with it much - just using the 'group' tag (which is just so brilliant)... will have to find a way of operationalizing the trial period from CLI. Well worth £28 I think.

Anyway I have this running on a Dell Optiplex 7010 which then feeds a Raspberry Pi 4 with RoPiee - I tried Volumio and its slow its just unusable - nor does it seem classical music friendly.

The problem I have is this: mConnect + RoPieee is gapless - yet BubbleUpnp is not (half second gap more or less) - and Bubble is much better at classical than mconnect. I'm thinking of trying UpMPDcli on the Pi4 with Bubble in the hope that problem may be solved.

Has anyone found a gapless renderer solution for RPi using BubbleUpnp as control on Android? Or a linux based renderer that could run on a Pi or thin client PC?
