If you are like me, you keep hacking your Ubuntu until you break it. My Ubuntu sound is having this issue in that the sound is working fine and then it suddenly degrades and starts breaking up.
I am not sure if it is my fault or a bug, but I have no time right now to dig out the reason, I have more important things to do, so to keep my music playing while I work, this is what I do: kill and restart sound – hi-tech solution isn’t it?
If you have the same issue don’t be shy, open your shell terminal:
You are welcome
