At this point, the Alexa Routines are not supported by the Bose systems yet. However, you should still be able to change volume or power on/off the system with the Alexa commands. Could I have you go to the Bose Music App and remove the Alexa voice assistant from the Soundbar 700 settings? At this point, when you reconfigure Alexa, it's important to follow the voice commands Alexa is asking to complete the setup. When Alexa prompts you to turn on the speaker with your voice, this is the point where the Bose Skill (not SoundTouch) is activated.
Let us know how it goes!

Thank you for the quick reply.
I'm able to turn on and off the Soundbar, however not able to ask bose to Mute for example. Is this a skill that is not added yet?
Thanks for the update!
Are you trying to mute the microphones on the speaker to disable talk back with Alexa or just trying to mute the sound from the source that's playing?
If it's the former, the only way to disable the microphones is to touch the mute button on the top of the speaker.
