Brian is having issues with his Amazon Alexa Echo Gen 2 and it's starting to have "hearing" problems. Leo says that it's probably an indication that the unit is dying. Brian could reset it. See if that helps. Also, he could plug in an external microphone.
But the good news is, that the new generation Amazon Echo is cheaper and better. He can also get the Echo Dot for under $50 that can connect to his own speakers.
