I use a hiresfi USB dac 5102 A, which demands a 96.000 Hz signal.
I apply this setting and play an album. JRiver starts correctly, but loses its setting when I skip to the next song or when I play another album.
After the settings are lost JRiver shows a Playback Problem, details: Playback could not be started on the output 'Core Audio' using the format '44.1 kHz 2ch'. (Et cetera)
