Ever since I connected alexa to turn on/off my xbox one S it makes a static sound when I...

Good news! I got Alexa control working again on the Xbox. Since Alexa sends the signal to the Xbox to turn the volume up/down on the TV, I went to TV control settings in the Xbox settings. Someone had played around with these settings and turned off TV control.
Now Alexa can control the Xbox/TV volume again.

Unfortunately, the problem with the Xbox app connecting to my Xbox continues. Any advice on this would be appreciated! Thank you for the responses so far!

For the sound bar, take a look at the HDMI ports and see which ports they are connected through. The preferred port is the one labeled on the TV and SB as "HDMI (ARC). Also verify that you are using an ARC compatible HDMI cable. I use an LG TV with a Visio
Sound bar and have never had an issue with the TV turning on the SB. Also make sure that the TV/SB are set to use the "HDMI-CEC" function as this is what allows the devices to control each other over HDMI connections.

For the Alexa control, I am not entirely certain this is an Xbox related issue, however it seems that way. I use the same feature/skill in my setup and have issues on one Xbox One S and no issues on a second One S. I have not worked this issue out, but based
on the behavior of my 2 Xbox's I am leaning to it possible being the fast power-on settings in Xbox. It seems as though the Alexa skill is unable to communicate with the powered off Xbox.

I totally understand the "just want it to work" mentality. The hardest part of being in tech support is not that people are "tech illiterate" it is that technology is very intimidating. It is twice as difficult when it is the significant other who simply
wants one button to make it all work.

You can only have one linked to it at a time Set up Alexa with Xbox One

Note Xbox Skill for Alexa may not be available in all locales.

Setup

To set up the Xbox Skill for Alexa:

1. Sign in to your Xbox.
2. Say “Alexa, open Xbox” and open the Alexa app, or search for Xbox in the Skills section of the Alexa app.
3. Select the Xbox Skill and sign in with your Microsoft account.
4. Follow the instructions to discover your console and pair it to your Alexa device(s).

If multiple people will be signing in on the same Xbox, see Use Alexa with multiple Xbox profiles.

Alexa commands for Xbox

Standard commands

For access to all the commands available for the Xbox Skill on Alexa, use the standard command structure, like this:

• “Alexa, tell Xbox to pause”
• “Alexa, tell Xbox to resume”
• “Alexa, tell Xbox to turn up volume”
• “Alexa, tell Xbox to turn volume down 5”
• “Alexa, tell Xbox to turn off”
• “Alexa, tell Xbox to launch Rocket League”
• “Alexa, tell Xbox to launch Netflix”
• “Alexa, tell Xbox to start broadcasting”
• “Alexa, ask Xbox what I can say”

Both “Tell Xbox” and “Ask Xbox” work for standard commands.

Smart home commands

Alexa smart home commands work for power, volume, and media controls. With smart home commands, you can drop the “Tell Xbox” or “Ask Xbox” portion, as in these examples:

• “Alexa, pause Xbox”
• “Alexa, resume on Xbox”
• “Alexa, turn the Xbox volume up”
• “Alexa, turn the volume down on Xbox”
• “Alexa, turn off Xbox”

The default device name in the Alexa app’s Smart Home Devices section is “Xbox,” but smart home commands will work if you change the name to something else – “Living Room Xbox” or “Zach’s Xbox,” for example. This becomes especially important if you want
to use Alexa with more than one Xbox. You can change the device name for your Xbox under Smart Home > Devices in the Alexa mobile app.

If you’ve recently used your Xbox One and there aren’t any other smart home devices paired with Alexa, you can drop the device name altogether, like this:

• “Alexa, pause”
• “Alexa, play”
• “Alexa, resume”
• “Alexa, skip forward”

Actually I have notice something weird regarding this issue. I am using my AV Receiver for the sound with the Dolby Digital 5.1 Recorder and with the "Ratings Collection Sound (Background Sound)" I am getting a static sound, but when I turn it back off there
is no more static. I still don't know the whole details, but that is one thing I have notice.

I had the same issue, after hours and hours of trying to figure a way to make it sync i found a way. you have to have a Amazon Alexa, go into settings on Xbox and connect your xbox to your Alexa, once connected your xbox now has the ability to take voice commands, you can ask Alexa to sync my Xbox controller to my Xbox you might have to say it multiple times but it does work I got my new head set and controller connected this way

Edit- just read the rest of the the thread and realized you don’t have a working remote currently, i connected Alexa when i had a working remote but couldn’t get the sync button to work to connect a new wireless headset. You might possibly be able to turn the Xbox on and ask Alexa to connect to your xbox not sure if it will work with out any controller input though
