Any guide or tutorial to setup a TTS Engine connected to a PulseAudio Sink?

Dear community,

When trying to setup MaryTTS and PulseAudio to provide TTS output to remote speakers via RTP, I went down the rabbit hole and got lost, see here in detail.

Is there any sample setup / tutorial from which I could adopt? I make only small progress as I do not have an example of what pieces need to be exactly brought together and how to configure them.

It would be great if someone could post the configuration settings of a working pulseaudio / TTS setup with an example rule creating TTS output so that it is clear what needs to be combined.

Best regards,
Peter
