Dear all, I updated all my devices to os 15 (ATV 4K 2021, a pair of homepod minis and my iPhone) and unfortunately the option to set my minis as default audio is not working. If I connect them via airplay as temporary audio system is all good, but if I try to set them as default, is not working...no sound is coming through my minis and on the TV says that it failed to connect and I can retry without success or change back the TV speakers. Do you have any idea how to fix this? (my tv is a Philips ambilight with 4K 60hz + Dolby vision and HDMI ARC option) Thanks a lot.
