I did mention the Docker requirement as it can be a sticking point, but I don't understand "slow transferring data". Are you saying that the Docker build itself was slow? Given that both BubbleUPnP Server and MinimServer have similar dependencies (Java) I'd assume the build size and duration would be very similar.

I've been using BubbleUPnP Server for years and I've never had, or heard of it crashing MinimServer. If you have any logs or crash dumps I think bubbleguuum and simoncn would be very interested.

BubbleUPnP Server deosn't allow you to create a DLNA proxy of a DLNA renderer so an OpenHome control point is required, which usually isn't a problem given the lack of decent options on iOS and the benefits of removing the queue from the phone.
I've heard of JPLAY but what's the Auralic app called?

I'm not going to argue with you there; it's worth every penny and then some.

I was trying to not be verbose, but since you asked...
I'm not clear on all the symptoms, I kept trying different permutations rather than troubleshooting through logs etc. I already had Minimserver running on Synology. BubbleUPnP Server running in the Docker container didn't play nicely with Minim running natively. Library transfer was painfully slow.

So then I uninstalled Minim and installed it in Docker.

I should preface by saying that my preferable control point is Jplay but it is not OpenHome. My second is Auralic's Lighting DS app. Auralic calls the connection to their streamer a "Lightning Connection" with UPnP a switchable option. With a bit more reading I learned that Lightning is their name for OpenHome and they say it is completely compatible.

So, with Minim in Docker my control points could see the Bubble proxy library, but when selected, they would not download the library data. Strangely, the Linn and Lumin apps did work, although they were slow and clunky. Unfortunately I find them woefully inferior and I'm not ready to go to apps that feel a decade old. Could be a routing problem, but other control points working points another direction and I may not have the bandwidth to sort that.

Bubble is a simpler solution although fewer transcoding options. I never was able to test if it would do what I want which is:
1. Have one end point that will transcode 2xDSD to 1x DSD, preferably with the Jplay control point, and leave all else untouched
2. Have a second end point that will transcode anything DSD to 24/192 and leave everything else untouched preferably with the Auralic Lightning DS end point

Lastly I tried just running two instances of Minim but now I can't get transcoding to work with Minim in a Docker container. I suppose that is another question for Simon.
