I’m thinking that something is broken in the current download of Balena-Dash. I can’t get a vanilla version to produce any sound - from either the headphone jack or over the HDMI port.
Is anyone successful at this? If so – could you please share your settings or what you did to make it work? I would LOVE for this to be something I can fix! I’m trying to build some video conferencing dedicated units for a tiny school. When it worked, Balena was by far the best solution.
