I've got foobar upnp playing to my Squeezebox working again.
But with MB I still get the same "error=BASS_OK".
When I try to play to my Panasonic TV, the TV first displays: "Request to play media was received...", and then "Cannot read file".
And MB then also displays "error=BASS_OK".
A new error log is in the same link I pm'ed you before.
PS
Do you have a suggestion to use either the 'Generic device' or the 'UPnPlay' setting in the plugin?
