So I recently (silly me) upgraded to the latest firmware -
Version 16.6 (build 83.1-61240)
Hardware Version 1.27.1.11-2.2
Ever since my arc would randomly reboot. It’s connected to a QN85B Samsung TV via eARC. When the problem occurs audio stops and the arc LED flashes white (booting) and then the TV switches back to eARC.
I discussed with Sonos support after sending diagnostics (diags aren’t very helpful, because they are only since last boot, so doesn’t catch the problem). They advised that it was because I’m running a piHole and blocking msmetrics.ws.sonos.com
I have selected in the Sonos app not to allow Usage Data Sharing, which is what this URL is for. But I guess it doesn’t care and keeps doing it, right? Hoorah for privacy…
I find it disturbing that even though I’ve opted out of usage data sharing, they still send it and if they can’t they will reboot themselves randomly.
Posting this here to save others time as I couldn’t find any hits on this issue. Hopefully someone from Sonos Development sees this and fixes their code to honour the users settings and not reboot themselves when they can’t phone home.
