just to update.  been using scan and go for a couple of weeks now.   No real problems.  a couple of times it did not work but for the most part it worked great. 

I really like it, except when well-meaning customers think I am stealing.   the other day, I went to the self-checkout to finish the checkout process, scanned the code on the terminal and started to walk out the door.  only took a couple of seconds.  Heard another customer behind me say something to the walmart associate watching the self-checkouts  about me not scanning the items in the bag, so I walked faster out the door  :-)   so much fun.  The associate knew what I was doing so nobody chased me. 

I have been saying that I was not going to subscribe when the free trial is up but I might after all.   Got six days left in my free trial to decide.   I really like the convenience of scan and go, and the nickel off per gallon for gas (only got three pennies off per gallon at krogers).    I started using a Murphy gas station in another town to fill up.  I really want to see where walmart is going with the plus.   

Sigh. Why am I always the only one to have problems like this?

it is not just you, just that there are no real answers.  Look like you tried all that you can do.   Over the past few months I have had similar issues.  sometimes it goes away on its own and sometimes it don't.  all I could do is to either rename or try to rephrase when I can. 

just a bit of brainstorming...Do you have something new in the room like a fan, something wifi/bluetooth/other electronic signals, or something that might be making different sounds that could interfere with sound waves?   did you move the plus, maybe too close to a wall where a microphone might be blocked.   when you give commands, are you facing or back towards the plus?   

Sigh. Why am I always the only one to have problems like this?

I was able to use Air Play in iTunes to stream music to my AVR ("Home Theater").

Can I take this one step further?

Can I tell Alexa to play a CD (that's already inserted) and Air Play it to my "Home Theater"?

What about telling Alexa to play a playlist from my iTunes, consisting of digital files, to my "Home Theater", using Airplay (not Bluetooth)?

I don't think Alexa knows about my computer yet.

It also doesn't know about receiver, I am working on that.  I can link my receiver to Alexa from the Heos app.  I'll do that sometime.

no true stereo, you will still have to pair it with another.   should be able to pair it with a home theater but a dot can do that :-)

check out the page on amazon.  It gives most of the features and specs.
