Do you have HDMI HD-audio codec driver module available on your system? The log message (showing "Generic") indicate that it's the generic driver being bound, not the HDMI codec driver. Well, of course I do have the module available, what a weird suggestion! ... except you're absolutely right and I'm terribly sorry for the noise. Turns out there's something wrong with the Debian kernel build and the signature of snd-hda-codec-hdmi is corrupted: # modprobe snd-hda-codec-hdmi modprobe: ERROR: could not insert 'snd_hda_codec_hdmi': Key was rejected by service Forcing the module load fixes the problem. And this also explains why this problem was only experinced by Debian users, which was weird and I should have paid more attention to this fact. Please accept my apology for this invalid bug report, and thank you for your quick and helpful reply. This is Debian bug report #942881, and message #20 lists a possible solution [1].
