I had the same problem on my Compaq laptop. If you will install the windows sound driver instead of the one that Toshiba uses, it might make it a LOT louder. It helped mine a lot. I'll try to find a link telling how to install the windows driver.

Ok......try going to windows update and do custom install. See if there is an updated Windows driver for your hardware. If there is, let it install and reboot and see if your sound is louder. This came from the R3000/z5000 forums but it should work the same on your laptop. Good luck and let us know if it worked.
