Cannot play music tracks on client side - rAudio as server: (Alternative 1)

[Sagnasty]

Running rAudio 20250322 on Raspberry Pi 3B+ Rev 1.3 hardware

After re-flashing each machine with the latest image and latest update, I tried using the Server rAudio (nfs-server) / rAudio Shared Data server feature and found the following:

I connected a exFAT formatted USB flash drive (contains two albums from different artists) to the server machine (192.168.1.50) and then enabled the Server rAudio feature.

I confirmed that the music file permissions are 777 on the USB flash drive.

After the library update completed, i confirmed that the functionality on the rAudio Shared Data server machine works correctly (can play music files and web radios, all relative data (song names, genres, counts, etc.) looks correct.

On the client machines, I then enabled the shared data client / rAudio and entered the static server IP address.

I immediately noticed that a message was displayed on the client machine indicating the a large library was detected and that the buffer size was automatically increased (from my original value of 81920 kb). Note: this increase did not occur on the server machine.

The client machine successfully created the storage mount as a NAS drive (192.168.1.50:/mnt/MPD/NAS).

The library database automatically began the update process, but never ended the update operation after about 5 minutes.

The library data looks correct and I could successfully play web radio files, but I cannot play any of the music files.

I reproduced this on two client machines.

Same here.

RPi 3B+ standalone, ok
RPi3B+ Shared Data master server (using rAudio Server) ok

RPi3A+ (Shared Data client - without reboot) journalctl -f gives:

RPi Zero2 W (shared data client - after reboot) shows library as:

and NAS section (should be lots of folders) as:

and journalctl -xe gives lots of errors like:

                                               Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
                                               If this causes problems, reconfigure your locale. See the locale(1) manual

Looks like something has gone wrong with Shared Data Libraries after latest update.
