No Sound coming from Mopidy on Raspberry Pi (NOT on MusicBox)

General
1

Hey all, been pulling my hair out on this issue I’ve been having. I’ve got it all setup, can go into a web client and queue stuff from soundcloud, but there’s no sound.

gst-launch-1.0 audiotestsrc ! autoaudiosink
and
aplay /usr/share/sounds/alsa/Front_Center.wav

both produce sound, but when queuing anything local or online there’s nothing. I am using analog output, gstreamer1.0-alsa is installed, and here is my config

[core]
cache_dir = /var/cache/mopidy
config_dir = /etc/mopidy
data_dir = /var/lib/mopidy

I have tried multiple webclients, autoaudiosink, alsasink, software mixer, alsamixer, all sorts of combinations, nothing seems to be producing any sound. aplay -l output just in case:

Quick edit: the log shows

every time I queue a song

Never seen this one. Have you installed pulseaudio here also? Did you install mopidy from apt or pip?

3

Mopidy installed from apt, all extensions besides mopidy-pulseaudio installed from pip. I used to have pulseaudio installed, but I uninstalled it using
sudo apt-get remove pulseaudio

4

Are you running mopidy as a service as as your user? Is the mopidy user in the audio group? The error message does sound like some sort of pulseaudio thing and the fact that it used to be installed is a bit suspicious.

5

Sorry about the late response, it is running as a service using systemd.

6

Exactly the same issue here.
Raspberry Pi 3 Model B
Raspbian distro (not Pi MusicBox)
Mopidy 2.1.0; installed from APT source, running as a service

gst-launch-1.0 audiotestsrc ! autoaudiosink WORKS
aplay /usr/share/sounds/alsa/Front_Center.wav WORKS

Still no audio from Mopidy.

Are not the same error. I suggest you remove your alsamixer settings and try to get the software mixer working first.

Thanks for the quick response!

I have change to software mixer and the issue and log file is exactly the same.

Regarding

…another post suggests this is no prob.

So the question is: Where is the problem then?

10

Why have you set this?

11

In general, it’s a really good idea to only set configuration values where you want a setting that is different from the default. This will make your configuration much smaller and simpler. It’ll also make upgrading to future versions easier.

Why have you set this?

[audio]

buffer_time = 10

Just trying to find a solution.

13

HI
I know this thread is old but a solution was never posted.
Was is solved for either of you?

Thanks

14

Did you follow the instructions at https://docs.mopidy.com/en/latest/installation/raspberrypi/#how-to-for-raspbian?
I redid that document not that long ago and it was all working.

15

HI
Yes I spent a lot of time in that Doc (my new “Bible”)

I am using the analog output and can hear sound during the Center.Wav audio test but not through Mopidy.

I have not played with the sound options yet and will try switching the output to “alsasink” as above.

Regards,

Pj

I

16

And are you running raspbian lite or the full desktop?

17

I am using the full desktop version.

18

Hey just to let you know I go the audio working with :
[audio]
mixer = none
#mixer_volume =
output = alsasink
#buffer_time =

Thanks for the Help, I will now attempt to setup streaming :slight_smile:

19

Thanks for the update. Sounds like a I actually need to try the desktop image myself and see what’s going wrong.

20

OK looks like on more recent versions of Raspbian Desktop, autoaudiosink defaults to use omxhdmi instead of alsasink. https://github.com/alexa/avs-device-sdk/issues/427

I will update our install documentation.
