For sm8550 you would need this patch for tplg

https://git.codelinaro.org/krzysztof.kozlowski/audioreach-topology/-/commit/d8ef47bc85700a7cdfabee5e06808d9f359b0a26

can you try this as the Container CAP Id changed for platforms from sm8550.

Kryzstof verified Display port tplg and these patches on x1e80100.


thanks,
