[PROBLEM] No audio or play and stop during reproduction

[Tim Curtis]

Sometimes its easier and faster to use one-at-a time swapping as an approach to isolating an issue rather than analyzing logs for example try swapping any of the following:

- Client
- uSD card
- Power supply
- Pi
- Network interface (use Ethernet instead of WiFi)

Ok thanks.
I will try but before that I need to understand a little better...

- Client. - ?  Do you mean another os?
- uSD card - ok
- Power supply - ok, but no undervoltage detected
- Pi - I can try with a 3b+ but the installation will be surely different 
- Network interface (use Ethernet instead of WiFi) - already using ethernet 


The installation is standard apart Plymouth for custom splash screen.

Today I encountered the issue: smooth regularly working. only during changing track sometimes it went playing with no sound. 
Re-changed track continuously and then after one or two ones again smooth...

By client I meant what you are using to connect to moOde (phone, tablet, PC)

I would connect via Ethernet directly to Router. Bypass the WiFi extender.
