Recalibrate Gen 2 Sub

I just feel as if my Gen 2 sub is severely lacking.  Added it to Arc yesterday and do not have the recalibrate option that from what I can tell is common with Mac or iPhone.  I do not have android device...

    Hello @Whistler,

    Thank you for the additional information and the fresh diagnostic. 

    The audio issues we are currently tracking with the Arc are concerning systems with no bonded surround speakers or Subs. Since you have both i’m giving your sub-woofer/ Arc communications some serious side-eye.

    It does look like your home theater system is changing 5g channels and this may be causing audio issues between the Sub and the Arc.

    Are you able to set a static channel for your 5ghz band in your router settings rather than have it set to “Auto”?

    You may want to take a quick look around and see if there is anything that could be running interference in your wireless network as well.

    Once I can rule out peripheral communication issues we can look more closely at the Arc itself. I appreciate your patience as we work with you on this issue.

    Hi Jean, 

    That is weird. Both my 2.4Ghz and 5Ghz have fixed channels. 1, and 44 respectively. The Arc is connected via Ethernet though. Sub is on Wifi/SonosNet. As for interference, there is a metal heater radiator on the wall next to the Sub. I have moved the sub to the other side (no radiator). Same distance to the Arc. I re-did Trueplay with my iPhone Xs. Makes not much difference. Did again with iPad Air 2. Sounded better again, but still not as great as with the Playbar. Sound remains more harsh, less bass and lower in volume than with the Playbar.  I myself are more and more convinced, the problem is more with Trueplay with my iPhone Xs. If i disable Trueplay, there is so much more bass! It just sounds bad as a whole then.

    Hello @Whistler,

    Thank you for update and additional information. 

    I’m sure you are fining this far more frustrating than I am and believe me I’m finding this frustrating.

    Are you able to  make any adjustments in the EQ or Surround Audio Setttings to balance the sound out?

    It does seem like something is amiss with the Trueplay in general on this, as you said, and hopefully this can be resolved through a software update.

    Hi @Jean C. 

    I have the sound tweaked now, so it’s acceptable for now. I’ll wait a few updates to see if things improve. Thank you for all your help and keep up the good work!

    What do you have your surround music playback setting set to? Full or ambient?
