RBi5 upgrade and flac files above 24/44 not playing

@BoJo
You can try change the DAC Model to BassFly uHAT with I2S Mic

Edit
It seems Kernel related, you may update to Volumio v.3.733 and choose HifiBerry DAC.
Audio playback is slow with hifiberry dac on Pi5 - Help and Support - Volumio Community
