Upnp not playing. - DRONE7 - 11-12-2021

I have the Upnp renderer turned on and configured.

I can play content from my Ubuntu PC and screenshots show all is configured, found, and sending...

MoOde shows the appropriate activity on the RPi ethernet port and in the main page (screenshot)...but no output and when I try to open the audio-info tab nothing happens.

Strangely....the MoOde main window shows "Radio" as the input in the 'circular worm' and 'live radio' next to the 'bouncy-castle' ??
and the little 'bouncy-castle' audio icon is active and bouncing!! :-).

Any suggestions ?

RPi4 MoOde 7.5.0 (but same problem last 2 versions)

Used to work fine.... Pulseaudio-dlna

This should be working...hmmm
This is weird "Volume mixer Fixed (0dB output)" as volume is Fixed in audio config.
So tried all other volume settings...software,hardware,null and still nothing.

It looks like VLC is sending a WAV stream which is why the moOde interface thinks this is a radio station. I don't know if that is just how VLC does UPnP, but it isn't like any other control point I've seen. Then you are using the Direct ALSA setting, meaning that your DAC has to support the WAV format (exact rate and so on). Switch to Default (plughw), rather than Direct (hw) and see if that helps perhaps.

I'm always on the lookout for something new to play with, but I crashed and burned trying to install pulseaudio-dlna, whether from the master branch or the python3 branch. Similarly for a more recent, forked version I found (https://github.com/Cygn/pulseaudio-dlna/releases/tag/0.6.1) which claims to have bug fixes. This, on my workhorse Linux Mint 20.1 system.

What version of Ubuntu are you running? I saw some evidence that pulseaudio-dlna was available as a package in the distro at one time but it's not available to my Linux Mint 20.1 system (derived from Ubuntu) nor to the Ubuntu 20.04.3LTS virtual host I run occasionally.

What startup options are you using with pulseaudio-dlna?

Hi Kent, I followed this how-to
https://www.linuxuprising.com/2020/10/how-to-use-pulseaudio-dlna-to-stream.html

though I recall that my Ubuntu 20.04 <upgraded from 18.04> already had installed and working this version way back 2018
https://github.com/masmu/pulseaudio-dlna

I have since found this... may try tonight when I get home.

@DRONE7

Curious. I thought I was doing essentially what is described in your first link, including using the Cygn fork of pulseaudio-dlna, but I must have screwed something up. (Granted, I wasn't doing anything with chromecast, but....)

I started over with the linuxrising HowTo and now I'm listening to Pink Floyd FLACs on a moOde 7.5.0 player as they stream from VLC on my Linux Mint 20.1 laptop via UPnP-A/V. Don't have any problem streaming MP3 or WAV files either.

I can control the volume either with the volume dial in the moOdeUI or the volume bar in VLC.

The audioinfo menu item is not responding.

My setup is moOde outputting to a CreativeTech USB/BT adapter using plughw and software mixer type.

As for metadata, coverart, and the like, nada. I'm not sure the VLC/pulseaudio-dlna combo is sending any useful metadata, e.g.,

Code:
pi@rpi3bp:~ $ mpc current

Liveaudio on T520 - VLC media player (LibVLC 3.0.9.2)

A postscript-

I took inspiration from your post and tried accessing the audioinfo script directly: http://moode.local/audioinfo.php

Apparently pulseaudio-dlna is transcoding. While playing any source file---FLAC, MP3, WAV---I get this output or something essentially like it

I invoked pulseaudio-dlna without any options. I know there is --codec option but I haven't explored it.

RE: Upnp not playing. - DRONE7 - 11-13-2021

I get essentially the same output.. (only with the device and it's mixer as appropriate) but no sound output and the level meters on the DAC do not respond indicating that nothing is being sent..or the volume is at zero.. but no volume settings work to change that software, hardware, or disabled.
I am baffled... especially as the same hardware worked previously. I will try a reinstall of MoOde and see what that brings.

Edit: Fresh install of MoOde and exactly the same problem. Fresh install of Pulseaudio-dlna and exactly the same problem. Giving up.

RE: Upnp not playing. - DRONE7 - 11-20-2021

Problem was at the Ubuntu end.

I tried with a new install of Xubuntu 21.10 where the pulseaudio-dlna package is in the official Xubuntu-repo and everything works straight out of the box.
