The Strangest Bug Of All Time - Audio back to 100% after screensaver

This almost feels like someone is pulling a practical joke on me. In the last few days I've noticed that at (seemingly) random intervals my gloabal volume was set to 100% by no fault of my own. This resulted in me nearly falling out of my chair several times and waking up my roomate once last night when I went to play some music or watch a video. I may have permanent hearing damage (I have some sweet PC speakers).
I just inferred that if I leave my laptop for some time, come back and unlock the screen, the volume will always be at 100%.  So I'm not blowing out speakers anymore, but still quite annoying.
Does anyone have any idea what might be causing this? I have to say this is probably the most hilarious bug I have ever experienced in the near decade I have been using Linux.

What a crazy bug! Is the volume change exactly correlated with the screensaver? If you make the screensaver take twice as long to activate, will the sound take twice as long to get messed up? I can't see how Xscreensaver (even the power management bits of it) could mess up a sound card. Unless you use one of those video cards that provide sound through HDMI.

Are you running any sound servers? And if you disable them does ALSA still fall victim to this bug? Which channel is maxing out, out of curiosity?

You should test this out (perhaps by disabling the screensaver and leaving the computer), as it sounds its a partial assumption you're making (which may not be helpful in narrowing down the true reason).

You're right. Its a very partial assumption. Im not so sure anymore its screensaver related. I'm really busy at the moment so I don't have a lot of time to fool around but hopefully I can come up with something soon.

Not sure it takes much time to set screensaver to disabled (depending on DE).

Are you using pulseaudio? Some applications don't work nicely with its flat volumes and make the volume go to 100%.
