However, I'll jump to it immediately if you say the word. Well, the situation is that I don't have any HDMI devices at all (either with HDMI outputs or inputs, forget HDMI audio), nor do I know anything about it. So if this doesn't work, that means that someone else needs to (a) reproduce your issue [and note, hdmi audio does work for some other people, so there must be something a bit more special about your situation, be it EDID data or more missed register setup], and (b) do the RE work to figure out what we're missing. It seems like testing out an old kernel is easy by comparison. However I don't hold out a huge amount of hope for it, since like you said, eld_valid = 0, which more likely indicates an EDID issue. If you're interested, some minor code inspection shows that at least some of the logic is in nv50_display.c:nv50_audio_mode_set. You could add prints in there to see what it's detecting stuff as. You could also add prints to drm_edid.c:drm_detect_monitor_audio, perhaps your monitor's EDID is different than what it expects. Looks like there are a few prints already, you could see what happens when you boot with drm.debug=0x06 which should output nouveau- and kms-related debug statements.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
