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
