If you want to customize your Windows sound device settings, then you should try Volumouse. This Windows program is extremely useful because it lets you make sure that your sound card has its best settings enabled, allowing you to get the best quality sounds possible from your computer. Of course, there are some things that you have to know about this program before you buy one. For example, it is not as easy as just turning on the PC and letting Volumouse take over - you need to know a few things about how to use it and what kind of settings it will use on your sound device, too.
Volumouse works on many types of computers, including Windows 95, Windows 98, Windows Me, Windows XP, and Windows Vista. However, you don't really have to buy one to get the best audio experience - you can use a freeware called Winamp to get the same results. However, you need to be careful with freeware because they don't always have the same quality settings as software like Volumouse. That said, you should definitely give freeware a try.
Of course, if you're really tired of using your PC and would rather not buy a new one, you could try using the free version. It is a lot more difficult to work with, but it is still a good way to get a feel for how to properly work with this Windows program. You will have to make sure that you set up all your devices first, though, because you won't be able to change anything in the settings if you have a certain sound card plugged into it. However, if everything works properly, you can always upgrade to the full version once you find it. You can find it online at my website.
