Hi,
SOF always passed 0 as dev_type to intel_nhlt_get_endpoint_blob() when looking
up the blob from the NHLT table. This causes issues since alsa-utils commit
3a47ef2487ed ("topology: nhlt: intel: support more device types and directions")
The dev_type is no longer always 0 in the topology embedded NHLT table resulting
lookup failures for analog codecs since they will have dev_type=4.
With SOF the dev_type is not used, we always use the SSP port index for looking
up the configuration blob.
The solution for the issue is to fetch the dev_type for the SSP port and feed it
back to the intel_nhlt_get_endpoint_blob() to be able to find the configuration
regardless of the assigned dev_type.
Regards,
Peter
