You have probably already done this, but mine was doing this and I unplugged the ethernet and power cable for 5 to 10 min and then re-booted it. It fixed it.
Bluesound Node N130
Hi I have replaced my Sonos Connect gen1, to Node N130. The Node can not work properly with coax cable it creates micro pauses and I can see that the display on my Simaudio flashes for one second, what is wrong? No problem on the Connect. I have tried two different cables same result. With optical cable no problem. The Node is connected with Ethernet cable (500Mbps).
Any clues
