Hello  
After 18 months is loyal service, my raspberry pi mopidy, iris server is broken.  
3 days ago I install snapcast server for iris as the latest version of iris has abandoned icestream2. I do a system update. By now I have lost the sound coming out of the PI as well as html streaming. Iris is reading the mopidy database and I have interface functionality. but as soon as I push play on a track, the iris interface starts playing without sound but in reality the PI has completely frozen. Not even the mouse curser works.

I have tried to role back but without success.

Can anyone share with me a mopidy config on a pi using snapcast with audio over http via iris? Below is mine.

# For information about configuration values that can be set in this file see:

# 

# [https://docs.mopidy.com/en/latest/config/](https://docs.mopidy.com/en/latest/config/)

# both defaults and this configuration file.

This looks like an icecast config to me

But I won’t debug complex setups like this. Restore back to regular audio output, get that working, then go from that baseline.

Thanks for the advice.  
I have erased the PI and have started from scratch.

But, Just so that I understand.

I wish to use both the PI’s HDMI output plus the snapcast http streaming.

Does the config line below cover both outputs ?

[audio]  
#output = autoaudiosink  
output = audioresample ! audioconvert ! audio/x-raw,rate=48000,channels=2,format=S16LE ! filesink location=/tmp/snapfifo
