Realtek ALC1220 not being recognized

Hey everyone,

I just replaced my old i5-3450 and the ASRock mainboard with a new 1600X with a new MSI mainboard, which includes one of Realtek's newer ALC1220 audio chips. Unfortunately, even though officially Linux support was added in 4.11, my system is not actually recognizing it. I did have sound output, but only through a generic HD Audio driver from the snd_hda_intel module, so I had a lot of distortion which makes using it currently impossible.

Here is what I found in the syslog:

Since the chip is pretty new, I haven't found any solution anywhere else yet, so I'm just gonna try my luck here first.

Re: Realtek ALC1220 not being recognized

I have the same audio chip on my Ryzen board, and I too have serious noise and crackling on my mic, but I have fixed playback with pulseaudio settings.

Have you found a solution?

Re: Realtek ALC1220 not being recognized

Haven't found a solution at all so far, but it doesn't seem like it is really needed. The noise and crackling only really seems to appear sometimes, otherwise the generic driver is working just fine. Still not the optimal solution since the Realtek driver should probably lead to better sound quality but as long as I'm not experiencing issues I'm fine with waiting. Gonna keep trying though.
