I would like to share my experiences using Volumio running on Raspberry Pi 4…
For a number of weeks I have been experiencing random crashes where Volumio would stop in the middle of playing a track via Tidal Connect and Volumio disappearing from the list of devices from Tidal app on my android phone. Also, I was then unable to ping my Raspberry Pi or connect using ssh (yes, ssh was previously enabled in /dev)
I spent a lot of time switching between the latest and the previous versions of Voumio and came to the conclusion it was not version dependent. I also tried a different SD card in case one of them had an intermittent fault.
Nothing had any effect and the random crashes kept happening, usually once per day. This was getting very hard to pinpoint the cause.
Then I started wondering about the CPU temperature and installed a Volumio plugin to find it was getting up to 55c. Not too high, and within spec for sure but compared to another Raspberry Pi 4 I am running (not a Volumio machine), it runs at 35c. The main difference is that the one which runs cooler uses a small fan for cooling whereas the one I am using for Volumio is fan-less.
I have now replaced the fan-less one with one with a fan, the same brand as I am already using for my other Pi.
I have not seen a crash for over a week!
While this isn’t conclusive proof, it is very encouraging nevertheless.
With the new case it has heatsinks not just for the CPU but some other devices on the board, including the DDR memory. With the original fan-less one, it only cools the CPU.
For anyone having stability issues with their Raspberry Pi 4 based system, I hope this is helpful
