I had a play around with this today, that's an afternoon I will never get back.....
Thanks for your pro-activity with this!
Some comments:
- for anyone wanting to try this out who doesn't own a Squeezebox:
there is a software version of a Squeezebox available, named SqueezePlay
LMS will see and treat that one similar to a physical Squeezebox device
(repeated warning: turn your volume down for possible extremely loud digital noise bursts!)
- I tried if I could get this to work with foobar2000
(it also has a UPnP output plugin available)
But that also fails to play music to my LMS/Squeezebox, immediately throwing some generic UPnP error.
So, it's off to the Lyrion forum and see what that may bring…
edit:
(I wrote and posted this before reading your latest post)
So the firewall could be an issue? I think I only have it allowing private traffic.
I'll see what happens if I allow public also. (probably tonight)
