After days of nagging about the 15.1.1 update I gave in and installed it on our system. After this a prompt to do Trueplay calibration on our Arc+Sub+2*One came up and I started that.

After multiple tries it still fails with a message (roughly translated from Swedish) “one speaker went missing during calibration”. During the calibration I hear all speakers working but noticed a very high pitched noice from one of the back channels right at the end of the calibration.

Support diagnostics: 2108779561

Try unplugging the speakers from power for a couple of minutes and rebooting your phone. Then retry Trueplay.

Thank you for your suggestion. Tried that and also rebooted the Boost connecting the system but still no go for TruePlay to complete.

Well, well hopefully next update will fix this. We live in a rural area with only our own WiFi and TruePlay completed two weeks ago without any issues when we moved around some furnitures so I am pretty sure the 15.1.1 update brought something, especially with the noice right at the end of the calibration process.

Same here. Never had an issue in the past. Gen. 1 beam and 2 gen 1 plays that I can’t tune. Same error.

This isn’t an answer. 


No, it’s a potential solution.
