2.12 Sound

2.12.1 Sound Settings

The Nintendo 3DS system sound settings allow for three different output modes that the user can choose from, specifically monaural, stereo, and surround. We recommend your application output sound using the sound setting selected in the System Settings. Because the application’s default sound setting is that specified in System Settings, there is no need for the application to intentionally change the sound setting. More specifically, there is no need to call the CTR-SDK function nn::snd::SetSoundOutputMode or the NintendoWare for CTR function nw::snd::SoundSystem::SetOutputMode. See the individual function reference entries for details. It is acceptable for the application to play sound using a sound setting other than that selected in the System Settings, but in these cases we recommend displaying a message to the user to that effect.

If there is a way within the application for the user to select the sound output mode used by the application, we recommend applying the System Settings sound setting as the default value on initial application startup. When using another value as the default value, we recommend displaying a message to the user to that effect.
If your application uses a freely configurable sound setting, be sure to consider possible detriments to the user owing to their sound environment. For example, if the user has set the System Settings sound setting to monaural and is using only one of the earbuds of the headphones plugged into the system and the application plays back in stereo or surround, the user will only be able to hear a portion of the sound.

Because there is only one speaker on FTR systems and their default sound setting is monaural, Nintendo recommends checking the sound with a sound setting of monaural.
