MPD httpd Streaming issue
Posted: May 3rd, 2020, 8:21 pm

I have MPD setup and working with MPDroid on my phone as well as outputting through ALSA locally on my Arch desktop (not enabled in config below, just did this to test).
However, both ympd the web GUI and persephone the GUI player on my MacOS are not outputting audio. I am not getting any errors. I have tried different web browsers and operating systems for ympd but something tells me its an MPD issue as persephone wasn't working either. I have also tried mixer_type "software" in MPD conf which opens up volume control on persephone and ympd but still no audio output. Any ideas?
MPD config:

playlist_directory "~/.config/mpd/playlists"
db_file "~/.config/mpd/database"
log_file "syslog"

Your "mpd --version" output doesn't show a version number, you omitted it.
Your log shows that MPD never played anything, and no client was ever connected.

Regarding the logs, I had just posted those thinking the settings would be a good indication of any possible issue but I didn't even think to show logs from connection. So sorry, I appreciate your patience and corrections!

Which program will connect to that stream?
Note that a MPD client only controls playback; it is not supposed to do the actual audio playback.

The logs above are ympd connecting. They both connect and receive the database info. They both control playback. However, ympd has a http stream option and audio is not output when enabled. I understand mpd is not necessarily intended for use as a streaming server so maybe I should look into an alternative, but I thought the httpd function would be perfect for my needs. I would seek help from one of those two clients but I'm not receiving audio from either one so I thought it might be an mpd issue. When I navigate to localhost:8000 I can output audio so maybe it is a client issue and not an mpd issue. What do you think?

If you receive audio from port 8000, but not from ympd, then this is a ympd problem which I cannot help with.
But I would seriously suggest not using streaming for your own personal use. That's up to you, of course.

I am in the same boat as the original poster, but using the ympd fork myMPD instead. Same outcome, it somehow doesn't connect to the HTTPD stream. Could you elaborate on your comment advising to NOT use mpd to stream audio? What's the point of the HTTPD output option then?
Thanks

The point of all of MPD's streaming features is to run some kind of (public?) radio station. Make music available to others.
But it is an inferior solution for listening to your own music files. Because streaming reduces audio quality, increases latency, increases CPU usage, increases memory usage, adds complexity and brings you lots of annoynances.
As I said, it's up to you, MPD gives you the freedom to do that in spite of all the disadvantage and in spite of all the superior solutions.
I keep wondering about people choosing MPD because they want to stream between their own hardware. That's not what MPD is about. MPD isn't particularly good at streaming - it has lots of strengths, and there are good reasons to use it, but streaming is not one.

Nowadays, streaming is synonymous with playing music on a PC. I like MPDs streaming feature capabilities for Sonos, Chromecast Audio an maybe other hardware. Adding some more features would be cool eg keep multiple outputs in sync, adding and removing outputs during runtime, routing audio and of course faster and fancier clients
In the meantime I enjoy a rocksolid Music Player Daemon.
