So, let me see if I have this straight
a) you decide to only Rip your SACD collection to an archive format that you know has zero Metadata handling capabilities
b) you then decide to painstakingly enter Metadata into a program that appears to offer no easy way to extract or export this same metadata??
and then expect Roon to ‘rescue’ this metadata and use it seamlessly along with the way they handle FLAC and DSF files etc??
So, in truth, not alone are you requesting that Roon add the ability to play ISO files [likely easily done]…but you [and from your post above] other JRiver, Foobar, A+ users will expect Roon to subvert their current Album ID process and ‘rescue’ manually entered metadata from a program that offers no easy way to export said data??
If and when Roon add ISO support, I’m not sure they will feel it’s within their remit to ‘rescue’ said data from Jriver et al…and will likely just offer the ability to Play the ISO…and their own method of ID’ing the ISO Album in question and applying their own metadata
I wonder how the others here will feel about such a solution…it seems to me that you are happy for JRiver to provide Replay functionality ONLY…but then expect Roon to provide Replay PLUS the full rich metadata environment…even though the Roon team have explained at length that this is difficult to do
