The Enigma streamrelay code is ours, others copied it, so not very likely the code is to blame.

Can you request the stream URL (with the RasPI IP) directly from your browser? And does that work? Is that the same URL as Enigma is generating?

There's nothing complex about at, Enigma generales a URL with an IP and a port, and then requests it like any other stream.

Is the rest of the Enigma config also ok? For example the ECM decoding settings for streams? And the local oscam has access to the NDS card to decode the channel?

Ok.

Afaik there is nothing that allows you to configure the output, audio should always be available, video if you select RCA as output.

I haven't got one of these cables myself, so I can't test.

Daarvoor zul je ergens iets werkends op moeten duikelen, wij maken al heel lang niks meer voor deze box, en er staan ook geen feeds meer online voor alles ouder dan OpenPLi 4.

It is not a headphone jack, it is an A/V port which combines CVBS video + L/R line audio. You need a cable like this to connect to it (note the 3,5mm plug has 4 connections):

Perhaps a H9.2S (dual tuner model):
