Q I want to listen to Amazon Music Unlimited’s Dolby Atmos music tracks on my home theater system. Amazon Music support says my subscription will only output Atmos to a few devices including headphones. But when I play the Best of Dolby Atmos playlist on my Roku Ultra streamer, the display on my Sony A/V receiver reads “Atmos” and I hear sounds coming from all of the speakers in my 7.1-channel system. Am I experiencing a real Atmos mix, or is this a case of wishful hearing? — Bill Heestand, Round Rock, TX

Q I’ve been checking out the JBL Charge 2 Bluetooth speaker but had doubts regarding its performance with metal and other heavy types of music. Would the Charge 2’s limited bass hinder the sound quality of heavy music in any way? —Abhay Bajpai / via e-maill

Q I tried to watch Cruella on Disney+ and was shocked by the poor video quality presented by my Roku streaming device. I was able to make the movie watchable by changing the color mode and lamp settings on my Epson HC 4010 projector, but still wonder exactly what happened. Have you noticed that some movies look notably darker than others? If so, does it have anything to do with high dynamic range (HDR)? —Gary Eickmeier, via email

Q I am new to the world of home theater, but I’m building a house soon and want to plan for the possibility of a home theater setup. I like the idea of having in-ceiling speakers running the surround sound. Is it possible to set up a Dolby Atmos system that exclusively uses in-ceiling speakers?—Jonathan Huizingh / via e-mail
