We currently have a set-up of several Raspberry Pis and Info-Beamers with monitors that have only DVI input. We are connecting to the monitors with HDMI->DVI cables.
Question: how to get ouput sound from this setup? We tried plugging a normal speaker to mini-plug port of Raspberry Pi, but that does not produce sound at all.
Any suggestions on how to get sound? We just need one Pi to produce sound.
