Administrators Hervé Posted October 12, 2021 Administrators Share Posted October 12, 2021 All off-topic posts deleted. Guys, I remind that this topic is about HDMI audio... Looking at the zipped EFI provided above, I can se that the OC config lacks the required, yet well-known, properties injection for HDMI audio: that of the HDMI connector type for the relevant iGPU connector/port (usually con1). framebuffer-con1-enable 1 NUMBER framebuffer-con1-type 00080000 DATA If audio is working from the onset, the above will enable HDMI audio. Of course, the exact connector used by HDMI output needs to be verified and adjusted as required (con2, con3). See the Whatevergreen user manual for details.
