Let's start off with this simple statement: Sample Rate matters. Period.
Samples are how your audio gets converted from vibrations in the real world into digital information and back. We are simplifying this drastically, but think about samples as frames in a video. Each Sample is a sort of snapshot of what was happening with the sound at any given moment. Play back thousands of samples very quickly, and we can approximate real-world sound. More samples means more detail.
Sample rate settings aren't easy to understand, but they can have a dramatic impact on your playback. Fixing these settings can also fix broken playback in a few cases. Here's how you can find and change your sample rate settings. We will use our own products as an example, but this workflow also applies to any audio input or output devices or programs you use.
First, you'll want to right-click on the sound icon in your Windows toolbar, located on the lower right of your screen.
Next, click on "Open Sound Settings".
Now, select your output device inside of the window that appears. For our purposes, we will be using the DFX Engine, which will be present in this list if you're using DFX Audio Enhancer or FxSound.
Once you've selected your output, click on "Device properties".
Under "Related Settings", you'll find this little button labeled "Additional device properties". Go ahead and click on that.
Now, navigate to this "Advanced" tab.
And now FINALLY, after all that menu navigation, you can choose your Sample Rate. Give yourself a pat on the back, and enjoy your audio.
Now that FxSound is free and we've moved to a donation model we've had to discontinue active customer support, but you can get help from the community at the new FxSound Forum.
