I too use my HomePod for white noise while sleeping. I play a single looped thunder storm track from my iPhone out of the HomePod mini. The track loops fine without any pause between loops on my Apple TV, from the phone directly, and on my iPad. As soon as I stream to the HomePod it randomly starts having breaks between loops. Sometimes no break, sometimes a second or two, and as much as 20 seconds.
It goes from loud booming thunder to deafening silence abruptly, and then back to loud booming thunder again. It’s making it impossible to sleep. Pretty crappy.
I’ve reset my wifi, to no avail. I don’t think it’s that anyway since I can broadcast the track from my phone out the Apple TV speaking with no issue. I’ve tried multiple HomePods (bought a new one out of desperation), and tried streaming from two different phones and an iPad.
Please fix this; I just want to sleep again.
Also, why isn’t there a white noise feature built in that you can ask Siri on the HomePod to play?
