Does it matter if left and right speakers are switched?

As long as the speakers aren't mirror-image pair, it should not matter which speaker you use for the left or right, or whether you decide to switch them from one side to the other.

How do I change my sound from right to left?

Scroll down to the Hearing section and you'll see a slider for left/right balance. Move the slider to the side where you would like to increase the volume level. For many audio sources, stereo sound features different sounds and levels in the left and right channels.
