Hi, Tiki
Thanks for your explanation..
I’ve expanded my testing with other music players.
Foobar2000 and Synology Audio Station both have the same issue.
For the ifi UPnP renderer device, inconsistent metadata should be a bug.
However, interestingly, to keep compatibility with certain brands, they’ve added support for the OpenHome UPnP API.
Since the ifi UPnP renderer natively retains OpenHome API support.
I’ve noticed that Foobar2000 and Synology Audio Station prioritize calling the OpenHome UPnP API, so they are not affected by the inconsistent metadata bug.
I will continue communicating with ifi-audio tech support, hoping to resolve this very basic error.
Thanks
