Created attachment 137870 [details] [review] [PATCH] Add one to EDID's audio channel count when passing to DC Thanks everyone for the debug on this one and especially Andrew for the patch. DC seems to take channel_count/audio_count to refer to the actual number of channels whereas the CEA EDID extension and our HW represent it as the number of channels-1. So as not to break other uses of this count (such as check_audio_bandwidth_hdmi()) this patch adds 1 when we get the count from the EDID. Can someone give it a spin? It's based on the latest amd-staging-drm-next branch but should apply on other branches as well.
