Hello @Peter_Zorn,
Thanks for contacting support regarding this issue. As mentioned by @ged_hickman1, we are currently working towards a fix for the Niam Mu-so and a few other Airplay2 devices but the fix is still in the testing stages at this time, and I am unable to provide a timeline for it’s release. You can read a statement about the fix here:

Thanks,
Noris
