Go back to the Start Menu and open the ffdshow audio decoder.

After it's open, go to the left column and click on Tray, dialogs and path. Then in the top right column, make sure one of the tray icons is selected.


Next, scroll all the way down to Mixer and make sure that it's checkmarked. Then in the right column, where it says Output speaker configuration, make sure 3/2 5 channels is selected.

For now, click on Apply and open an MP3 to see if that did anything. Whether it did or didn't, go pack to ffdshow audio decoder and in the right column, checkmark Volume. And adjust your speaker's volume.

Keep in mind, this will only work if your MP3s use this codec.
