I have not noticed a new music issue on my Zenith...
However, I still have the issue that any restart of the Zenith will automatically start music playing on all my outputs, whether DAC connected by USB, LMS speakers on the network or UPnP connected Receivers/DACs... The same happens on individual players when I start them: for example when I turn on my USB-connected Devialet Expert Pro, it immediately continues to play whatever was playing before there, despite my having stopped the music there. Only radios may be exempt from restarting to play, but not sure. I will have to test. that again. Local and Qobuz tracks definitely start playing each time I restart either the Zenith or the amp/speakers/dac...
