I have a problem with playing anything that uses sound. I use a desk top pc running windows 10 with bitdefender and Malwarebytes. Today I tried to play my Amazon music and had an audio loop of "important security" being played over the top of my music, same with utube and memory sticks that played normally a few days ago. I presume I have picked up a bug from somewhere but how do I find it and get rid of it. I have done a Malwarebytes and a bitdefender scan and they found nothing. Help would be appreciated please.
