Hey @alvester – as mentioned in the thread @philr linked above, there’s simply no way for us to support WMA on all the different platforms we support Roon runs on, and it’s only come up a handful of times since launch.
My recommendation would be to read over the thread and consider doing a conversion to something like FLAC – this will be a bit perfect conversion so you won’t lose anything with regards to sound quality, and that will also ensure your files are compatible with all sorts of devices and programs for years to come, including Roon.
Let me know how that sounds and we’ll make sure you’re happy here @alvester.
