With the default configuration PulseAudio only sees a single "speaker" port, and assumes that controlling the Speaker element has some effect, which is not true in the digital mode. To work around this, let's add a special path configuration for this card to disable hardware volume. It would be better to disable hardware volume only in the digital mode, but I believe there's no way to automatically figure out which mode is in use, and requiring the user to tell which mode is in use at any given time would not be user-friendly.
