When is the Sonos Arc sound dropping fix coming out?

SO many posts for SO long. I and SO many others are absolutely FED UP with how buggy and unsupported this “premium” product is. It pains me every time I watch that I have to power cycle the Arc in hopes it will have continuous sound.  And with having to keep eArc off, a premium feature I paid for, for some hope of stability on power cycling just to get through a movie is inexcusable.  
 

When is the fix coming??  I am concerned it is hardware at this point, given how long it has been widely known.  If that ends up being the case, I expect full refund.   I have Sonos everywhere in my home, inside and out.  At this point I want to put it all in one giant box and send it back.  I am THAT fed up with the ecosystem I used to love.  

I suspect it’s a TV firmware update that’s needed, but meanwhile have you perhaps tried switching off HDMI-CEC on all ‘other’ devices connected to your TV HDMI ports, or if that doesn’t solve it, maybe switching the Arc’s connection over to optical instead?
