Disabling the Volume Dial in Ubuntu on a Toshiba Laptop

I have a Toshiba A135-S2356 laptop running Ubuntu. A major annoyance is that when the laptop is actually in my lap, it is too easy to accidentally brush against the volume dial. So, I find myself wanting to disable the volume dial. You can do this by going to the Ubuntu menu and selecting System -> Preferences -> Sound. At the bottom of the devices tab is a list of Default Mixer Tracks. If you set the Default Mixer track to something like Mic Boost (assuming you’re not recording anything), when you brush against the volume dial, it will not mess up your volume.
