My Lumia 1520 speaker goes in and out

[Nakia Johnson1]

I bought this phone off eBay it was working okay, but the speaker goes in and out when I play videos and when I play Xbox mobile games on my device. Has anyone ever experience this issue. I am on prepaid with at&t, they do not do mobile insurance on any of their prepaid phones. (Haven't been through this before, this is working my nerves)
