Thanks for the detailed description. I have apple losssless set to "native" and flac (within the apple lossless server setting) set to sox/faad. Stock touch is now handling 192 alac file I presume by down-sampling from LMS, and edo touch delivering indicated 192 on same alac 192 file.

On touch with edo and touch without edo, when i go to "more info" it gives me the file's encoded sample rate, but does NOT tell me if down-sampling is taking place. For instance, touch with edo playing 192 alac file tells me "apple lossless, 192." Touch without edo tells same story, though of course it must be down-sampling to play.
I can't find any transcoding / sample rate informatiion on web ui - if by that you mean either "advanced settings" or "web remote control." I'll see if i can figure out how to run "debug" and check settings in log. > Note that the transcoded to...
