I know this is an older thread, but a related question: I'm streaming from my phone with jRemote2's Chromecast. My FLAC files play fine, at their bit rate and sampling. But ALAC files are transcoding to 320 Kbps. Is that normal or do I have a setting wrong?
(My ALACs are all 16/44.1 from CDs, yes, from back in my iTunes days. It'd be a lot of files to convert to FLAC. It's an Android phone, MC 27.0.20 is on my Windows 10 PC. Interesting result, suggests this is a Chromecast/jremote (interacting?) issue, I think: I played the same ALAC song with JRemote closed, by selecting the same Chromecast device (DLNA) from the MC Playing Now list on the PC. Then when I opened jRemote2, it indicates that it's playing 16/44.)
