OLED no longer works in latest release

[mariusp44]

This is based on mpd_oled and cava. It used to show artist, album, song, track time and spectrum provided by cava. However, this is no longer working in the latest release. It now only shows mpd_oled standard information such as date and time and IP address only.
It used to be home environment for cava as I reported and fixed here: #1975. This time it is different problem.
mpd_oled starts as a service with each song start as before however cava is not started. I tried to investigate but no luck as of yet.

I can confirm that it works as expect in release i20260216. mpd_oled starts cava and shows spectrum and track data, e.g. artis, title, progress etc. mpd_oled properly generates pipe and temporary cava configuration file and spawns cava:

root       37337       1  4 15:40 ?        00:00:04   /usr/bin/mpd_oled -o 6 -f 25 -c fifo,/tmp/mpd.fifo
root       39221   37337  5 15:41 ?        00:00:00     cava -p /tmp/cava_config_fdM72G

Once upgraded to the latest i20260415 it stops working. Only mpd_oled is started and display doesn't even show playing track only date and IP address.

I have verified binaries of both mpd_oled and cava and they are all the same based on MD5 checksum. That means, the problem is somewhere in rAudio bash scripts but differences are vast to pinpoint where exactly the problem is.

Please try the UPDATE.

If I install image i20260415 it won't allow to update any further at this point even though it seems there is an update 20260424 on github: 20260424.
Similarly, image i20260216 would only update to 20260415 and that's when it breaks the OLED. Like I said before OLED works fine in firmware i20260216.

Currently running firmware and rAudio version:

This worked and also fixed the OLED, thank you!

@rern - latest update 20260509 doesn't allow to change "Spectrum only" setting. It stays on no matter what though spectrum OLED works. Only that it won't switch between spectrum only and additional information with track album progress etc. Not sure if this is intentional but that's what it is.

I suspect this might be related in some way to my problems with LCDChar not working with this same release (#2098)
