Thanks for the pointer Tiwai!
The problem on my board at least seems to be AZX_DCAPS_POSFIX_LPIB,
which seems to get enabled by default. Some of the HDMI entries further
down?
My chip is called 1022:1457 so I did something like this:
/* AMD X370 */
{ PCI_DEVICE(0x1022, 0x1457),
.driver_data = AZX_DRIVER_GENERIC | AZX_DCAPS_NO_TCSEL |
AZX_DCAPS_SYNC_WRITE | AZX_DCAPS_SNOOP_TYPE(ATI) },
Not sure what to call the entry.
I didn't notice any change with SYNC_WRITE on or off really.
Here's a way to list the pciid of you sound chip btw:
lspci | grep "HD Audio" | cut -d " " -f 1 | xargs sudo lspci -n -s

Title:
Microphone distorted sound on ALC892/1220 on AMD chipsets
Status in Linux:
Confirmed
Status in linux package in Ubuntu:
Won't Fix
Status in pulseaudio package in Ubuntu:
Won't Fix
Bug description:
Not sure if I'll report this upstream but there is definitely an issue
with microphone recording on my desktop, this is not happening on my
laptop which has a different codec.
Already tried all workarounds possible, no luck. Only with my desktop
with this particular motherboard. No issues in Windows, the sound
recorded in there is distorted and has some static and robotic tone on
high-pitch.
