Alert popup: "JSON parse: unexpected end of data at line 1 column 1 of the JSON data" - feh123 - 07-15-2024

Hi

I have a Raspberry Pi +3B with a Hifiberry Digi+ Pro HAT. I updated to 9.0.4 (Bookworm 64Bit) several weeks ago using the Raspberry Pi Imager.

It all worked well and it is still working fine. However it did give the error alert: Alert popup: "JSON parse: unexpected end of data at line 1 column 1 of the JSON data" - this alert kept repeating. This did not effect the installation as far as I could see. I loaded my library and my radios and they all worked.

Now I do see an issue with my Moode - not sure it's definitely related to the alert. I have been running Moode for several weeks with all the default settings. But I was looking at the defaults  and I noticed wifi was enabled so, as I have a wired connection, I disabled the wifi.

There were no error messages but after the restart I had lost all the sound on playback. Both of radios and my library. I did check moodeutl -l and that showed no issues. I have repeated this on a fresh install and I get the same result. Is wifi on essential? Maybe I am missing something obvious or doing something completely wrong but I thought I would report it.  

Incidentally HiFiBerry's lastest digital feed HAT is the Digi2 Pro - it's not on the Moode list. I have a Digi2 Pro on another Moode device - it seems to work fine using the Moode listed Digi Pro.

Yours

Reboot and then post the contents of the startup log.

The log can be viewed via the SSH command moodeutl -l or downloaded via the Logs section in System Config, or via Menu, System info from any of the Config screens. The startup log will be at the end of System info output.

I paste the log file. Rebooting showed the error again and I have lost sound. So this seems to be about rebooting rather than wifi.

Ah! What is happening is that the sound level is being reset to 0! It's working fine now. Many apologies for not seeing this straight away! It's just I have never seen the sound level reset before (my poor excuse!).
