I recently bought another Sonos Connect unit. The first was set up to play Pandora and IHeart. It is connected to 3 separate wired speaker sets. They are all grouped together under 3 speakers. I bought my second Connect to add a CD player and, if possible, a turntable to my existing 3 speakers grouping. I first connected just my CD player on my second Connect and it only worked part of the time. I also purchased a RossMX42 Mixer to add the turntable to my system. It was recommended from the Community. I haven't attempted the second input device because just the CD player hasd only worked on occasion. I, initially, would like to connect my CD player and have it work all the time. Once that is accomplished, I would try to connect both the CD player and the turntable into the MK42 and run the out line into the in line of the new Connect. My original set up with Pandora, etc. has always worked. None of the new equipment attempts have worked. HELP!!
