Thanks for letting me know that timestamp. I have been running my squeezebox touch for the last 3 days without issue, so I am not sure if it would need the full 4 days to get into this state, but it’s been responding as expected on my end so far.
I’m going to ask QA to take a look at the diagnostics around the 4:19PM timestamp you mention to see if there is anything strange regarding the commands, but as far as I can tell Roon is still sending the proper commands and it may just be the Touch that’s not responding to them properly.
I need some more information here to have a complete report for QA to review though. Can you let me know the model/manufacturer of all your networking gear including router, any switches, range extenders, powerline adpaters, ect?
Also, what version of Squeezebox firmware are you running? You can check this by going to Squeezebox settings -> Advanced -> About and seeing what version is listed there.
