Playbar keeps switching to TV.

Approx once per day (not yet investigated if this is at a constant time), the Playbar, which I invariably keep tuned to TuneIn Classic FM when switched off, unilaterally switches to select TV Audio. It started doing this about a week ago having steadfastly stayed on Classic FM for many months beforehand barring the occasional power cut or network reset when it reverted to “No music selected”. I am on auto-update, so assume this “feature” coincided with a firmware update. Two reasons this should not happen.  1) there is no optical feed to the playbar, 2) The App switch “TV Autoplay” is off.

A different Room (comprising a pair of Play 1 and a Sub) has a similar set-up, and steadfastly remains on Classic FM.

This playbar in years gone by featured in a full surround system, but now stands alone as a simple radio - turn it on with the power button and up pipes classic FM. Having to dive into the App for this every time now is infuriating. Is this a known bug - and/or is there a workaround, please?

    Bump

    This happened sometime within the last couple of hours - submitting a diag in case I was fortunate enough to catch it.- 1317513510 

     

    Anyone from Sonos TS looking in?

    Experimentally, if you have TV Autoplay enabled on the Playbar, disable it and see if this behaviour stops.

      TV Autoplay not been on for months. I tried - for experiment - turning it on for 5 mins and back off again a few days ago to no avail. Thanks for your thought.

      Just reread your post a bit more carefully! So this Playbar is not even connected to a TV?

      If so, maybe that is the problem - it is being used in an 'unnatural' way. I accept there is no reason I can think of why that should be a problem, especially when it is a recent change.

        It has been working as a Classic FM radio not connected to a TV for about 8 months. This phenomenon started about 10 days ago. I do not know if this coincided with a firmware upgrade but as I am on auto-update that is my current theory. Nothing else has changed.

        The TV connection - when it existed - was of course optical - galvanically isolated, so I really can’t see the lack of connection having any bearing.

        Have you tried just powering it off for 30 seconds and on again, since this problem arose?

        Although it makes little sense, could you put an optical cord in the Playbar?

        Otherwise it will be interesting if the diagnostic throws up something.

        Good idea on the power cycle - will go and do that now and reset to Classic.

         

        Edited to add done. Came back to life “no music selected” - so I tuned it in to Classic FM - now a waiting game.

        And at some stager it flipped in the last couple of hours back to TV - so I changed it back again to Classic FM - will try to catch it when it next flips - I have an “always on top” mini controller on the PC open - but not easy.

         

        I wonder if it will flip if the radio is actually on (rather than standing by) - let’s try that.

        Right - I’ve diagnosed it.

        If set as a radio and playing, all is well. The side buttons work correctly on thr playbar, and the volume can also be raised and lowered and muted using the TV remote control that has been programmed to the bar.

        If set to a radio station but stopped, it is vulnerable to reverting to TV sound. The precipitant is… the infra red remote control. Pressing the volume down button on the remote dutifully turns the volume down on the play bar (despite the radio being stopped). However, pressing either Volume Up or Mute on the infra red remote reliably sets the playbar to be in TV mode.

        A diagnostic that captures this anomaly has been submitted - 1972503313

        It has only occurred since mid/late April. I will try reprogramming the remote to the bar if I can remember how to do it, in case there has been a memory location shift in a recent update that requires it to be rewritten.

        Edit: Reprogrammed the remote - made no difference. Since Sonos TS don’t sem to be frequenting this thread, I’ll send an email their way with a summary.

        An update for those following this thread: Just had a convivial chat with a chap from Tech Support (which followed a few red herring email exchanges with their front line) - and the query has been flagged into the deeper bowels of tech support.

        As part of this interaction I did a factory reset of the play bar, all to no avail.
