I’ve only had my Rossini player for about two weeks now, but I’ve already had to power cycle it no less than five or six times.
One common factor seems to be that over time a connected Mac will no longer see the USB input of the Rossini player. It simply won’t exist. Rebooting the Mac does nothing, you have to power cycle the Rossini player for the USB port to come back as an option for output from the Mac.
The last time I did that, I fired up Mosaic, and it strangely was giving me only the option of changing the filter. The “Audio” options to alter upsampling, mapper and the rest were not present, and when I selected “Display,” the options to turn the display on and off and the toggle for the logo were not given as options, either.
After a power switch power cycle of the Rossini Player, all was back to normal.
