Hi, I followed this guide (Streaming Spotify to your Pi) to install Mopidy on Pirate Radio.
The default volume level was very (very!) loud so I opened the config file (/etc/mopidy/mopidy.conf) and found an error as it was using the ‘software’ mixer instead of ‘alsamixer’.
My config file now is:
[audio] mixer = alsamixer [alsamixer] enabled = true card = 0 control = Master
Now the output volume level is in sync with ALSA and I can change it with alsamixer in ssh.
The problem is that now I can’t find the name of the ALSA control to use inside mopidy.

As you can see known mixers on card 0 are none! If I run this command (according to GitHub - mopidy/mopidy-alsamixer: Mopidy extension for ALSA volume control):
pi@pirateradio:~ $ amixer scontrols Simple mixer control 'Master',0 Simple mixer control 'Capture',0
Maybe the problem is that I’m using Pulseaudio?
