Is the DP cable connected?
if its not connected the dsp will throw this error.
due to this issue I did workaround this issue by modeling it as
conflicting device to Speaker in x13s ucm.
I see in your ucm setup its not the case.
which is why you might be hitting this issue.
Can you try
amixer -c 0 cset iface=MIXER,name='DISPLAY_PORT_RX_0 Audio Mixer
MultiMedia2' 1
aplay -D plughw:0,1 some-wav-file.wav
both with and without display connected.
