Hey there @Bennie3
I stumbled over your message, after having the exact same problem. How did you manage to "reconnect" the soundbar to the TV?
Could you give me a few short instructions on this? To set this up via Alexa/Google Home, did you use IFTTT?

Nothing so far from Bose works to fix this issue.
The Bose sycophants/acolytes/fanboy/girls on this forum have a lot of 12 step procedures to temporarily fix this but none of them admit there is actually a problem-it's always something besides the Bose appliance that's at fault.
No workaround should be necessary.
My Sony HDMI receiver I've used for a couple of years never.had.this.problem with the same TV.
Bose obviously isn't a HDMI/TV provider so they're having problems figuring out how to make it work.
They have no expertise in this area so therefore the HDMI problem.
I've given up and placed an on/off switch in line with my TV.
If i turn off the TV power completely and turn it back on it sees the Bose.
The reason I don't turn off/on the Bose is when I do, the subwoofer driver bottoms out "BOOOM" "CLACK". I can hear the sub voice coil hitting the magnet! Bose doesn't handle on/off transients on power cycle very well, another design flaw.
As you can tell I'm still very much upset with my expensive purchase not working as well as my cheap little Sony receiver did.

I had the same issue, I did reset Tv and soundbar 700 but it didn't work out, finally I changed the HDMI cable, it solved the issue.
It seems Bose HDMI cable is not a quality one.

Ik heb nu sins een dag de Bose 700 set maar wat een drama met het HDMI arc verhaal het werkt echt voor geen meter. Ook niet als je cec uit zet dan heb ik ook geen geluid. Ik ga de boel terug sturen en Sonos bestellen. Erg jammer van bose.

My tv used to play audio thru the sound bar 700. It no longer works. I went thru all the motions described by you. I have a Sony kdl 60EX700

I was finally able to get my ARC to work perfectly!!!
First, I turned the power off on both my SoundBar700 and my Samsung TV.
Then I disconnected my HDMI cable from my SoundBar 700.
Then I connected that end of the HDMI cable to my old Sony STR video/receiver and it all works perfectly again!
As of this date there are 50+ pages of complaints on this one issue. Let's face it, as much as we all think we are owed a fix to this issue, no one at Bose is going to resolve this.
And don't get me started on the Bose remote backlight shutting off in half a second.
