Suggested speakers not working

I know there aren’t many speakers that are gate Terd to work I followed this Video and even bought the one shown in the video using her link. This is the third speaker I’ve bought from Amazon and whenever I set up the pi it just plays through the hdmi speaker or nothing at all. What are some possible fixes as this seems to be more of a pi issue then a speaker issue ( I’ve also tried two different pis as well)
