Lost volume control with stereo Homepods
Since updating to tvOS 16.6 I have found the volume control on one of my stereo (original) Homepods no longer works via the Siri Remote. The left-hand Homepod volume can be changed with the top touch pad but using the Siri Remote has no effect. The Mute button also has no effect. Bizarrely the right-hand Homepod volume control & mute still works.
I have tried:
a) restarting the Homepods & restarting the Apple TV 4K
b) Ungrouping the Homepods and pairing them again
c) Ungrouping the Homepods, replacing the left-hand Homepod with a spare Original Homepod and pairing it with the right-hand Homepod (which suggests that resetting the Homepods will not fix the problem)
d) Restarting the Siri Remote ( If the volume buttons on your Apple TV remote stop working - Apple Support )
I have run out of ideas. I am hoping that a future tvOS will fix this issue.
