Hi Srini,

I tested this series on SM8550 with tplg in [1] and ucm in [2]. But the kernel output errors attached below. Headphone does work properly without DisplayPort in the ucm.

What could be the possible cause of this? Is there any significant change from sc8280xp to sm8550?

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.
