For whatever reason, the sound capability of most hybrid video/still cameras is clearly inferior to their video. Some cameras don’t have any external audio jacks, while others have a microphone input but no headphone output. Very few cameras sound as good as their pictures.
The audio preamplifiers in these hybrid cameras tend to be weak — often an afterthought in design. Most camera preamps are noisy, have very limited headroom and poor metering display. They also produce highly compressed audio files.
