At a glance, the main difference seems to be: [drm:drm_detect_monitor_audio], Monitor has basic audio support -[drm:drm_edid_to_eld], ELD monitor Panasonic-TV +[drm:drm_edid_to_eld], ELD monitor VSX-923 [drm:parse_hdmi_vsdb], HDMI: DVI dual 0, max TMDS clock 190, latency present 0 0, video latency 0 0, audio latency 0 0 -[drm:drm_edid_to_eld], ELD size 9, SAD count 1 +[drm:drm_edid_to_eld], ELD size 13, SAD count 8 This is getting pretty much to unknown territory for me, so if anyone knows anything better, please chime in! I think I'd try using the TV's EDID with the VSX-923 to see if the ELD/SAD difference makes, uh, a difference. Something like this: 1. connect directly to TV 2. copy /sys/class/drm/card0-HDMI-A-1/edid under /lib/firmware with some sensible name, e.g. panasonic-edid. the exact source path may vary depending on HDMI port etc. 3. make sure you have CONFIG_DRM_LOAD_EDID_FIRMWARE=y 4. use drm.edid_firmware=HDMI-A-1:panasonic-edid module parameter to tell DRM to load the edid from /lib/firmware. again, the connector name HDMI-A-1 may very depending on HDMI port you use, do check. 5. connect to VSX-923; this should now use the EDID (and consequently ELD/SAD) from the TV I haven't actually tried this myself. *grin*. Let us know what happens. Thanks.
