Well, 18.4, general release yesterday, brought all this back. Using the HomePod pair and the ATV device to play tv audio, the sound now drops out of one pod or the other, switching back and forth. The audio does not drop out, come back, drop out again, as it did with 18.2, creating a motorboat sound as it did back then. But the audio, while constant, will switch to one pod or the other. If I look at one pod, the light up top will be off, while it’s lit on the other one, then this switches back and forth. I have restarted all devices, and the issue continues. I noticed it immediately after 18.4 was installed and hoped a restart would clear it up. I’m quite frustrated as when this works, it makes for a very good home theater system, but every software release screws something up. I am completely fed up with them and will either just use the tv speakers or look at a reliable soundbar. This setup is not reliable in the least.
Now the issue has even extended to playing music playlists. The sound is switching from one pod to the other, with the volume on one diminishing to almost inaudible, while the other stays elevated; this rotates back and forth. This software has really messed up the ATV and HomePods. Are any others noticing audio issues, even separately from tv audio?
