When I try to use audio (YouTube, Audacity, LMMS, etc.) I get this kind of skipping noise every couple of minutes (on average, sometimes it starts happening every few seconds) and so it makes watching videos and making music (or even listening to it!) almost impossible (for example "Hello" becomes "Hel-el-el-el-el-el-el-elo").
When I restart pulseaudio, it seems to stop for a couple of minutes, and then starts again. My audio was fine a couple of weeks ago, and so I have no idea what the problem could be
