I don't think vc4-fkms-v3d supports audio. You still have the same drivers for HDMI, which are activated by option:
dtparam=audio=on
You should install dtoverlay=vc4-kms-v3d (or vc4-kms-v3d-pi4 in case of RPi4) and remove dtparam=audio=on. When you run alsacap or look at audio info in Moode, you should see, that HDMI audio is different.
After switching to vc4-kms-3d:
It looks a bit better if you upgrade system, at least alsacap shows devices, but mpd still can't open audio.
