Unfortunately, that are last messages from asoc-audio-graph-card

Mar 23 08:39:17 devuan kernel: [   11.694427] asoc-audio-graph-card
soundcard: lookup for GPIO pa failed

and no, it is not detected:

root@...uan:/home/user# cat /proc/asound/cards
 0 [H58006000encode]: HDMI_58006000_e - HDMI 58006000.encoder
                       HDMI 58006000.encoder
root@...uan:/home/user#

Hmm. Is it possible that EPROBEDEFFER is playing with me again?
