Can't hear anyone in voice chat

I can’t hear anyone speaking in voice chat even when their name pops up like they’re talking, and I’ve tested it with friends and everyone can hear each other and even hear me, yet I can’t hear them. I’ve checked all in game settings and my computer settings, as well as following the solutions that blizzard has for troubleshooting vc problems but nothing has worked. I haven’t changed anything in my setup so I have no idea what’s causing this. I’ve tried submitting a ticket to Blizz support but they just gave me the same list of troubleshooting options that I had already tried. Parental controls are off, I can hear all other game noises normally, and discord calls work fine. Please help

Make sure your device is set as your default device in your settings, I thought I had this done already but didn’t and it ended up fixing the issue for me!
