    * <code>alsactl</code> is used to control advanced settings for the ALSA soundcard drivers. It supports multiple soundcards. The following example demonstrates changing the settings for the default sound card by remounting the filesystem read-write, changing the settings, storing them, then remounting the filesystem read-only.
