This is an untranscoded stream. If you want the stream to be transcoded to wav, the URL needs to be:
http://192.168.1.9:9790/minimstreamer/*/RP/$!stream.wav
OK, here's the log using that URL.

The stream is still not being transcoded. I think there must be some issue with your MinimStreamer configuration. What do you have for these properties?
stream.transcode
stream.converter
stream.options
Edit: Please ignore this, see below.

My apologies, I copied and pasted the wrong URL. It should be this:
http://192.168.1.9:9790/minimstreamer/*/RP/$!transcode.wav
RE: Converting flac audio streams for internet radio use - FakePlasticDunk - 24-03-2023 18:21
Ah! OK. Well that was far more exciting, the NP30 hung and then rebooted itself. Herewith the log.
RE: Converting flac audio streams for internet radio use - simoncn - 24-03-2023 21:22
This is sending a stream header size of 4GB-1. To send a stream header size of zero, change the URL to this:
http://192.168.1.9:9790/minimstreamer/*/RP/$!transcode-0kb.wav
RE: Converting flac audio streams for internet radio use - FakePlasticDunk - 25-03-2023 17:09
OK, this time the NP30 just hung; log attached.

The NP30 doesn't like a zero-length WAV stream. It closed the connection and then sent a byte-range request, which MinimStreamer rejected.
From the log, it looks like you still have ogg in the EXTINF line. This shouldn't make any difference because the transcode instruction is now part of your preset URL.
I suggest you try transcoding to L16. For this, the URL is:
http://192.168.1.9:9790/minimstreamer/*/RP/$!transcode.L16
If this doesn't work, I think all options have now been tried.
RE: Converting flac audio streams for internet radio use - FakePlasticDunk - 25-03-2023 17:50
I definitely don't have ogg in the EXTINF line:
#EXTM3U
#EXTINF:-1,[RP] Radio Paradise
http://stream.radioparadise.com/flac
and the NP30 and MinimStreamer have both been restarted multiple times since the file has been that way, so that's odd.
I just tried the L16 URL above, and this time a short burst of sound, followed by 'End of Stream' message on the NP30 front panel. Log attached.
Thanks for your methodical determination and patience with this.

This log shows only that the NP30 closed the connection after 0.3 seconds. There is no byte-range request and no information about why the NP30 closed the connection.
I have investigated why MinimStreamer is still using ogg for the RP stream. This would happen if you have restarted MinimServer by selecting Restart from the minim icon rather than completely closing MinimServer and relaunching it. This is a bug and I will think about how it can best be fixed.

I think we've reached the end of the road with the NP30 and uncompressed lossless streams then. Compressed lossless is looking rather unlikely too given our flac experiments.
For the record, I selected Rescan rather than Restart (in MinimWatch) each time I changed the playlist, which seemed to stop and restart MinimServer each time.
