Thanks Dmitry for testing this out.

This series changed the Jack event names by removing HDMI string from it 
as suggested, did you update the UCM to reflect this?
I have pushed changes required to 
https://github.com/Srinivas-Kandagatla/alsa-ucm-conf/tree/topic/x13s-dp


Can you also try to  clean the asound.state restart the pipewire.

I think this is to do with ucm changes requried for new jack name.

I have tested this with

kernel: 
https://git.codelinaro.org/srinivas.kandagatla/linux/-/tree/dp/sc8280xp-6.10-rc1?ref_type=heads
ucm: https://github.com/Srinivas-Kandagatla/alsa-ucm-conf/tree/topic/x13s-dp
tplg: 
https://git.codelinaro.org/linaro/qcomlt/audioreach-topology/-/tree/topic/x13s-dp?ref_type=heads


with the above on my x13s, I can properly do switching between dp0,dp1 
and speakers with no issues.

Can you try them?

thanks,
Srini
