A:AnswerYes it will work outside the US. Only some features will be unavailable, such as ordering food and making calls to name a few. Everything else works, I had some Hue bulbs, a Home mini, and a regular Google Home in Ecuador and everything except for those few features worked.
A:AnswerBetter question is what doesnt it do, the options are endless, mine controls tvs, game system, dvr boxes, lights, pc and im adding more as we speak.
A:AnswerProbably not...I do not see any hook up options that would let that work. Unless you could hook it up with Bluetooth. But I doubt an old receiver would have that option. It is not a great speaker but it works good enough for us. Really only use the receiver for the turntable.
A:AnswerFor the most part I'd say no.
However, if you're playing music like spotify you can "cast' it to the speaker. Personally I don't know why one would do that if the speakers for your computer are better.
Other than that I don't know of other ways to do what you're asking.
