As a small tweak, I'm using a Realtek RTL8153 chip USB ethernet dongle with an Audioquest Jitterbug filter instead of the onboard ethernet port on a RasbPi 3 running piCorePlayer 3.5.0 as suggested by Klaus aka Soundcheck (https://soundcheck-audio.blogspot.co...ne-part-8.html). When I boot piCorePlayer, it (smsc95xx driver?) does not look for and find the network on eth1 (my usb ethernet dongle) but continues to look for the network on eth0 (the onboard ethernet port).

from dmesg:

There's a workaround where I can get everything to work. In Squeezelite I can select "choose player". There, my player's name "piCorePlayer" shows up twice. If I choose the other "piCorePlayer" then it will access LMS on my desktop server and all my network files and eveything works fine. Just curious if there's any suggestions for troubleshooting to get the network to be recognized in a normal fashion.

I added the line "smsc95xx.macaddr=(my mac address for the usb-ethernet dongle)" to config.txt but with same result. Thanks.
