///
/// This function returns a vector of strings containing
/// the names of all available audio playback devices.
///
/// If the operating system reports multiple devices with
/// the same name, a number will be appended to the name
/// of all subsequent devices to distinguish them from each
/// other. This guarantees that every entry returned by this
/// function will represent a unique device.
///
/// For example, if the operating system reports multiple
/// devices with the name "Sound Card", the entries returned
/// would be:
///   - Sound Card
///   - Sound Card 2
///   - Sound Card 3
///   - ...
///
/// The default device, if one is marked as such, will be
/// placed at the beginning of the vector.
///
/// If no devices are available, this function will return
/// an empty vector.
///
/// \return A vector of strings containing the device names or an empty vector if no devices are available
