I am not able to test this environment directly.
Are you able to ssh in and run this command:
cset shield -c '0-0'
cset shield
Thanks, I try my best and will report… 
The Plugin has been accepted into Volumio 3 plugin store.

Hi Pete Do you have any idea when it will be available? It’s not there on my RPI 3+ based streamer with latest (stable) beta Volumio 3
Hmm it should be already there? – the PR was approved Add Music Services Shield to Volumio 3 Plugins by petecallaghan · Pull Request #33 · volumio/volumio-plugins-sources · GitHub
It’s under Music Services (wrong category IMO)

Perhaps time for a plugin search?

Ooops :-D.
Wouldn’t be a bad idea. But I agree that Music Services ain’t the right category for this plugin. It ain’t a radio station, nor streaming service

Very interesting.
Is it possible to use it effectively for Roon?
The plug-in doesn’t have explicit support for roon. However, if you SSH in, you can run the script files that add a named process to the user shield, or set the process priority.
You can then listen and decide if roon benefits from the shield.
For example, if the roon process is called ‘roon’, then execute the following to add it to the shield:
sudo sh ./moveprocess.sh roon user
Funny, in the code it’s under the System Hardware category 
When I look at the processes with the top command, I can’t tell which one is Roon.
Is there any way to find out?
You can call cset shield -v to see the full list of processes in user or system.
You can also try nano /lib/systemd/system/roonbridge.service to see what the Roon service command is
Thank you.
I don’t know what to do.
I will leave the result of the command.
Could you please advise me?

I’ve drawn a blank here. I can’t seem to figure out the Roon process name. Anyone else got any ideas?

I don’t know which one is Roon’s process either.
/data/plugins/music_service/RoonBridge/RoonBridge/Bridge/RoonBridge
seems main body of Roon process.
Many thanks for this plugin. I tried it yesterday with the last version of Volumio (plugin version 1.3.1). Works great, I thought Volumio was good but it does make a big improvement on sound quality. I wonder why it is not simply included in Volumio settings.
Thanks for your work, Flifli
