Now I found following email thread between you and Alex with patch which configures HDA mixer via that SHDA method: https://www.spinics.net/lists/platform-driver-x86/msg03206.html But looks like that patch was never included into mainline kernel... Seems it would be needed in some part (to not break older Thinkpads) for that LED support in alsa mixer about which Takashi Iwai wrote. -- Pali Rohár pali.rohar@gmail.com
