I was running checkbox and I went through a sound portion, got bored and killed the test. Problem is that something has happened to my sound as a result. It sounds really scratchy like it's way too loud for the speakers. What has happened and how do I fix it? Any ideas? Perhaps there's something I can run that will re-initialize the sound? Note that a restart did not help, which is the most alarming.
...OK, that was weird. Changing the volume seems to have fixed it. Should I leave this here for others to find it?
