An HDMI converter to what other connection? HDMI and DisplayPort can carry audio, DVI and VGA can not. For those, you will likely need another cable for audio, such as a 3.5mm to RCA stereo cable running from your laptop's headphone jack, assuming your projector or other audio equipment supports RCA-in for audio.
