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.
