In case it is useful, I added some logging in and around snd_acp6x_probe()
in sound/soc/amd/yc/pci-acp6x.c and got the following information:

snd_pci_acp6x 0000:c3:00.5: pci->revision=112
snd_pci_acp6x 0000:c3:00.5: acp-audio-config-flag=0
snd_pci_acp6x 0000:c3:00.5: flag snd_amd_acp_find_config(pci)=16

When I add logging to acp6x_probe() in sound/soc/amd/yc/acp6x-mach.c, no
logs are output.

This was with kernel 6.12.9.

My last message was misleading. It's not that acp-audio-config-flag is 0,
but rather that reading it was successful. Let me try this again, and using
hex values that are probably more familiar:

[    5.692748] snd_pci_acp6x 0000:c3:00.5: pci->revision=0x70
[    5.692828] snd_pci_acp6x 0000:c3:00.5: read acp-audio-config-flag:
success
[    5.692855] snd_pci_acp6x 0000:c3:00.5: acp-audio-config-flag value: 0x10

After updating alsa-ucm-conf from upstream (overwrote /usr/share/alsa/ucm2
from the latest at https://github.com/alsa-project/alsa-ucm-conf), the
device is recognized as a digital mic. Would it be possible to get these
kernel configs enabled for amd64 in 6.12 bookworm backports and 6.13 trixie?

CONFIG_SND_SOC_AMD_ACP_PCI=m
CONFIG_SND_AMD_ASOC_ACP70=m
CONFIG_SND_SOC_AMD_LEGACY_MACH=m
