Created attachment 295269 [details] alsa-info output ###Overview I am running Arch Linux Kernel version 5.10.15 on an MSI Godlike X570 motherboard, and I believe Alsa is having issues with the Dual ALC1220 Codecs. I saw that this has been an issue before in the and looks solved, but for some reason, my Alsa utilities are crashing when trying to access my sound card (using Alsamixer and amixer). I think this might be related to [Bug ID 195305](https://bugzilla.kernel.org/show\_bug.cgi?id=195305). ###Steps to reproduce amixer -c 0 ALSA lib simple_none.c:1544:(simple_add1) helem (MIXER,'Master Playback Switch',0,1,0) appears twice or more cannot load mixer controls: Invalid argument ###Expected Result amixer should print data about my sound card. ###Actual Result amixer crashes with the following error messages.

I have tried solving the issue in a variety of ways, including explicitly setting the kernel module snd-hda_intel model name. I also experience the same bug in a fresh Arch Linux ISO, which rules out most configuration issues, I think. I reviewed your documentation, and it looks like my next step is to file a bug report. I already reached out to the Arch Linux community, and you can review my post at the following link. I have also attached the output of alsa-info.sh to this post. https://bbs.archlinux.org/viewtopic.php?pid=1949255#p1949255 Let me know if you need anything else from me, I appreciate all your work, and look forward to your response!

Could you try to pass the model=,dual-codecs to snd-hda-intel module (note the first comma that means an empty value for the first slot that is for Nvidia HD-audio)? If this works, we can cook up a patch to enable the quirk easily.
The fix worked! Thanks so much Takashi! I am curious what the root cause was.
There is a special setup for the boards with the dual codecs, and it's applied only for the known PCI SSID, where your device wasn't listed there. Now I submitted and merged the fix to upstream.

The fix will be included hopefully in 5.12-rc2 kernel and backported to stable trees later on.
