The Wii Remote has a built-in speaker that is used at certain points while using the Wii. The following information describes how to adjust the volume of the Wii Remote's speaker.
Not all games use the built-in speaker.
Turning the speaker volume down can extend battery life of the Wii Remote.
This procedure must be performed on all Wii Remotes you wish to adjust the volume of.
Press the HOME Button on a Wii Remote that is synchronized with the Wii console.
Select the Wii Remote Settings option from the Home Menu.
Move the cursor over the "-" and "+" buttons to increase or decrease the volume levels. You will hear a sound from the speaker each time you adjust the setting. The sound approximates what the volume level would be at that setting.
