I´am using Volumio with a Meridian Explorer (USB) on the RPi. The Meridian Explorer can show with the help of three LEDs which sampling rate the music has.
I have setup Volumio to make an upsampling up to 192kHz (Fastes Sync Interpolar) of my music which goes via AirPlay to the RPi. The Meridian Explorer shows me, that the upsampling does not work, I only see one LED, which indicates 44.1 kHz.
Has anyone an idea to that behavior?
