ALC1220 not working properly


I'm using Fedora 25 with Kernel 4.11 on my new Ryzen System with a X370 Taichi. At first, the audio was working fine but after a reboot it's just a bunch of random noise. Isn't the ALC1220 supposed to work fine with Kernel 4.11? The card is used by the driver snd_hda_intel and when I blacklist that, nothing else grabs it. Also it shows up as HD-Audio Generic. I tried to enable snd_hda_codec_realtek and snd_hda_codec_generic, but they didn'rt grab the sound card. Does any of you know a solution for my problem?


Fedora 27 fresh install, crackling audio

Were you able to solve this issue? I’m actually having the same issue with Gigabyte X370 K7.



Unforunately not. My speakers are working fine but whenever I try to use a microphone, it sounds very bad and my speakers just output weird noises until I reboot the machine and unplug the microphone.



Yea, while testing I actually made that happen useing hda-analyzer tool. But yea I’m went to usb audio as I try and figure it out.
I didi notice this:
sysdefault:CARD=Device front:CARD=Device,DEV=0 surround21:CARD=Device,DEV=0 surround40:CARD=Device,DEV=0 surround41:CARD=Device,DEV=0 surround50:CARD=Device,DEV=0 surround51:CARD=Device,DEV=0 surround71:CARD=Device,DEV=0 iec958:CARD=Device,DEV=0 hdmi:CARD=NVidia_1,DEV=0 hdmi:CARD=NVidia_1,DEV=1 hdmi:CARD=NVidia_1,DEV=2 hdmi:CARD=NVidia_1,DEV=3 hdmi:CARD=NVidia,DEV=0 hdmi:CARD=NVidia,DEV=1 hdmi:CARD=NVidia,DEV=2 sysdefault:CARD=Generic front:CARD=Generic,DEV=0 surround21:CARD=Generic,DEV=0 surround40:CARD=Generic,DEV=0 surround41:CARD=Generic,DEV=0 surround50:CARD=Generic,DEV=0 surround51:CARD=Generic,DEV=0 surround71:CARD=Generic,DEV=0 iec958:CARD=Generic,DEV=0
Both codecs are read as DEV=0, which is probably the main cause of the dual codec issue.



My mainboard has only one ALC1220 codec, so the dual codecs shouldn’t be the issue
