|On some laptops, there are two or possibly three volume controls. One is the Windows/driver control and (on windows 7) appears on the tray on the bottom right. On many laptops, there is a software volume control from the laptop manufacturer (sometimes on the desktop, sometimes in the tray), and there may also be a manual volume control slide or up/down buttons. A manual slide will be independent of software, but the button type may be connected to the system mfg's software control. Any (or all) of the controls that you are not using need to be moved to the maximum setting so that the one you are using will have the full control over your volume.|
All of that said, if this does not fix the problem, you are under warranty, so contact the manufactures support for more help on this before doing anything else.
You have to be a little bit crazy to keep you from going insane.
