For the Marantz I specify that it can do 96000, but this seems to be over-ruled by the protocolinfo for raw, even though I'm using wav.
I would quite like to use 'flow' on my Marantz, but I can't work out any combination of settings that will avoid 2 sets of resampling for my range of tracks. It doesn't really matter, but it's baffling. I don't know how many users will want to dive into this level of detail to keep the resampling down to a minimum whilst get a stable result. I understand that people want fading etc (I don't), so it's good from that perspective. I don't really understand why anyone would want to use 'No Higher', and I don't understand why, even without that, LMS is still ignoring the 96000 capability I specified. I just hope it's not going to cause too much confusion for users, and work for you to explain it all. +-------------------------------------------------------------------+ |Filename: UPnPconf.txt | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=25522| +-------------------------------------------------------------------+ LMS 7.9.1 on VortexBox Midi box, Xubuntu 17.10, FLACs 16->24 bit, 44.1->192kbps.
