A:AnswerI don't think so. The alexa is for controlling your soundbar and other devices that you can configure to work with the soundbar. I am not aware of a way to control smart tv apps with the soundbar.
A:AnswerYes, the Soundbar 700 features an IR receiver. This means that it can be used with third-party universal remotes that communicate with an IR transmitter. Please contact the manufacturer of your remote for setup assistance with programming their remote.
