There is no meta data that is shared through the COAX so you’ll only see the rate. If you have the Jr. set to auto input select, that should work with the latest Jr. firmware.
The button to the left of the display selects the input as well as the menu which you have already discovered by displaying the firmware levels. A long press of the button goes to the menu and a short press selects the input.
So, you can select the input you want which defeats the auto selection. And the auto selection is just another input selection.
I have not noticed any differences in the volume levels, but others may disagree. I usually leave the volume level at 85 and then adjust the volume from the remote. My preamp has a motorized volume control and it is hard to dial in the desired volume from the remote.
Aha, cool, thanks, auto mode is not itself automatic. But has to be selected. Just did not want to send anything below 1000Hz to the tweeters by accidental UPnP!
Played some tunes that cause clipping on my multichannel interface if it is set at line level. Five dB away is OK tho. The DSJr was at 100 with no issues. So maybe the 92 was only for the DSSr…
