Sound 'blips' when streaming audio

Okay, first and foremost, I have scoured the internet for this specific issue, and every post I have found (this forum included) addresses something related but not exactly like what I'm dealing with. So here goes.

I'm experiencing slight 'blips' in sound when playing streaming media. I notice this mostly on youtube, but it occurs on other streaming platforms such as bandcamp, facebook, etc. as well. The 'blip' is usually very short, and it's not necessarily scratchy, or static-y. It just sounds like a slight distortion in sound. They're fairly frequent, although not frequent enough to make the streaming audio completely unrecognizable. Just enough to be incredibly irritating. By the way, this only happens when I'm visiting my brother at his apartment, where he lives with three other people, and has a slightly slower internet connection than I do. There's two other people at my house (although there used to be four other people), and I have a faster connection, and I pretty much had no problems. Can anyone help me out?
