Is it compatible with the 55ub820v-zh

Not familiar with LG range but from a quick look at specs there should be an optical output that , from my Samsung experience, works well with the sound bar and an optical ‘cable’ is included with the purchase. Hope that helps.

I have heard that Alexa's voice volume cannot be adjusted in the sound bar and may-be too loud at times ? Is this true ?

I have the sound bar in a medium sized bedroom and I personally think the alexa voice level is just about right.
