The difference is access permissions. Your alsa process runs under the mpd user, yet the fifos are in home dirs of other users. How about trying to configure them into a directory which all users can access, e.g. /tmp, would it help?

Hi,
Now I have understood, I guess that's what also the mpd oled was adding the fifo part in the mpd conf directly as tmp folder.. To be accessible mpd user.. But if I know how to do it... Or will be great but like I said I am not experienced user.
Thanks a lot for finding the root cause of the issue

Fifos need two processes - one creates it and writes into it, another reads from it. When placing fifos into /tmp (where every user can write files - look at output of command ls -ld /tmp ) and creating them with appropriate permissions (e.g. everyone read), the communication can be established.

The creating/writing process is configured in the alsa config. I guess the peppy meter is configured in PeppyMeter/config.txt at master * project-owner/PeppyMeter * GitHub .

Hi,
1. I will create the fifo in /tmp then assign 755 permission
2. Set path to new fifo file in config. Txt
3. Change also the new fifo path in asound.conf
4. That's it?.
Thanks

Maybe the peppyalsa plugin creates the FIFO itself, I have not checked.

Just try and see, eventual errors/problems can always be fixed.

In order to create the fifo I need to create it in home volumio with mkfifo myfifo so I guess does not creating. I will do it and announce.

Hello my dear friends ,

I am so glad that the peppymeter plugin is fully working on my setup .
Like phoman pointed out and the end it was problem of integration fifo with mpd .
I have perfomed exactly the steps that you sugested and it working .
I am so glat that it is working .
Maybe this great plugin can be updated for Volumio OS

PS: now remain only the issue with hanging the pepymeter picture when killing the peppymeter process. It does not switching to Volumio UI just show the meter picture

My best regards .
Florin
