It appears that the GH4 (and possible other models) do not play audio through the headphone connector when HDMI is connected. This is in playback only. Monitoring recording works fine. I have several external monitors I use but none of them has audio out. Is there a solution to playing back audio and video in such a case?
I think simplest thing is to get monitor with headphones out.
Otherwise, add it to GH4 issues topic.
