@support Since Roon doesn’t upmix stereo content to multi-channel, I need to switch the playback settings in Roon from multi-channel when playing 5.1 content to 2 channel when playing stereo content so my McIntosh MX160 can do the upmix. This is an annoying task but doable.
The problem I’m having is that Roon seems to relentlessly output 7.1 channels as indicated by my MX 160 input format display even when 2 channel output is selected on Roon. Since the MX 160 sees it is getting 7.1 channels it doesn’t upmix even though there is only two channels of sound and the rest is silent. Is it a Roon issue or could it be that the Mac HDMI output add the extra channels? Either way is there a fix?
My set up is Roon 1.3 on a Mac Mini (Sierra) music server with USB connected drive and an HDMI connection to a McIntosh MX 160
