Homepod disconnects or stops playing music from itunes randomly

Homepod was just updated to 13.4. I did NOT notice this issue previously but others are reporting the exact same issue on other forums.


The first thread details the issue perfectly.

When using the homepod as a speaker from iTunes it will randomly stop playing music and display a dash like this "-" next to it. If I deselect it and click it again it will start playing sound again. If I stop the track and play again, it will start playing again.


Playing from windows 10 PC, fully updated.

iTunes 12.10.4.2

Homepod 13.4


The issue seems to happen less when I use the homepod as the only device checked to play music to. If i check other devices, like the apple TV and computer itself to play as well the issue happens more often. My WiFi is solid with no deadspots, I've done a speed test and poor mans site survey with my iPhone to test speeds with no issues. Also to rule out WiFi as the issue i can play from my iPhone to the homepod and apple TV without the problem.


I suspect its an iTunes issue or possibly the homepod struggling to stay in sync with iTunes. Please read the other threads before suggesting solutions already purposed as I've tried them all.


This clearly seems like a bug but I don't know where to submit bug reports for the homepod.


Thank you in advance.

So no dice on turning off the homepod features, however I have found a pattern in the packet capture correlated with the failure. I no longer think this is an issue with the homepod, but a problem solely with iTunes.


Every 30 seconds, iTunes sends a TCP message to homepod port 7000 with an OPTIONS message that provides cseq number, user agent, instance ID, and a remote ID. Between these messages, the homepod will send a TCP Keep-Alive to my PC from port 7000 every 6 seconds. After 4 of these, iTunes sends the options message.



When the issue occurs, that 30 second interval TCP options message does not get sent. That's why the other poster was encountering the issue at the 28 second mark each time. That is the refresh interval for this options message.


We can see in the packet capture, the TCP fin message comes as soon as the 30 second interval passes without the options message being sent from iTunes:


This leads me to believe that it might be possible to spoof this options message to the homepod using a 3rd party tool, therefore keeping the stream alive even when itunes fails to send the options message itself. That will be my next task.
