Hi – I don’t know if I should start a new thread or not but, I have the same issue. I added hdmi_force_hotplug=1 hdmi_force_edid_audio=1 and hdmi_drive=2 to the bottom of my /boot/config.txt and I have no audio via HDMI. I am connecting it to my sound bar.
I have just upgraded to retroPie 3.0 and I use the Pie 1.2+ B
Any help would be appreciated! :D
