Correct, a single HomePod, not a stereo pair. It is the only HomePod in our home, there are no others.
Yes, I have restarted the Roon Core. I have also reset the HomePod itself, after which it did work with Roon; however, as soon as the music queue emptied, it stopped working again. I’m happy to attempt that again if you think it would help debug.
I think the next step here is to enable some diagnostics on your account so our technical staff can get some more insight into what’s going on here.
However, before I enable this feature, I’d like to ask for your help ensuring we gather the right information.
First, can you please reproduce the issue once more and note the time that you start playback (but there is no sound). Then respond here with that time, and I’ll make sure we review the diagnostics related to that timestamp.
Now that I have the timestamps, diagnostics have been enabled on your account. The next time your Core is active a diagnostics report will automatically be generated and uploaded directly to our servers
Once that’s been received, I’ll be sure to update this thread and pass the diagnostics over to the team for further analysis.
I spoke with the team about their analysis of the diagnostics report. They’re seeing some errors that appear to show that something is blocking the connection between Roon and the HomePod and they have some questions they were hoping you could clarify:
Just to confirm, you did a full factory reset on the HomePod, correct?
Can you confirm how the HomePod is connected to the network? If you connect it to a different access point is there any improvement?
Do you have any antivirus or firewall software running on the Core machine? If so, is there any change if you temporarily disable them?
Question 2. The HomePod is connected via 802.11ac wifi. The house was wired at construction for a UniFi system. There are 5 UniFi wireless access points connected to a core switch by in-wall CAT6 cabling. Each access point covers a different section of the house. I just moved the HomePod from one part of the house to another and made sure that it was re-connected to a different access point. Nothing has changed. See the image below that shows the status screen for the HomePod in the UniFi app. Below that is a screenshot showing the relevant topology of my home network. If you need any more details, please let me know and I am happy to provide them.
Question 1. Yes, I had reset the HomePod completely (remove it from Apple Home app, reset, reboot, re-initialize through iPhone). It then worked for a little while but then stopped. Let me try that again and I will get back to you in a few hours with the results.
Here is what I’ve discovered after multiple resets.
If the HomePod does not connect to my iCloud accounts, it works fine with Roon. But as soon as it connects to my iCloud accounts, the symptom shows again.
Following are two screenshots showing the status of the HomePod from within the iOS Home app, which seems to be the only way to interact with the HomePod. The first shows that the HomePod is NOT connected to my AppleID. In this configuration, Roon works. The second shows that the HomePod IS connected to my AppleID. In this configuration, Roon does not work.
Thanks. By rebooting the router, I assume you mean reboot the entire network. Yes, I have done so, including the router, switches, WAPs, etc.
(Rebooting just the router won’t affect this situation, since both Roon Core and HomePod are on the same subnet 192.168.10.0/24. Packets from one to the other would be handled “in Layer 2” by the core switch itself.)
