thank you for the report.

SOF 2.5 (and SOF2.6 still) is opt-in for this generation of hardware and 
we only provide DSP topologies for a limited set of devices (refer to our 
readme at ). In 
short, you need a laptop with a HDA (not Soundwire) codec to use this 
release of SOF.

.. for SoundWire enabled systems, we recommend sticking to the stable 
SOF2.2 release (v2.2.6 the latest). This is also guidance we have given to 

I know this is less than ideal, but the recent SOF releases require a new 
version of the DSP topology description, and we have limited options to 
redo (and test) the descriptions for older hardware, so we've had to pick 
a subset of hardware we support in these opt-in binaries.

This reveals your system has a SoundWire audio codec and unfortunately
not covered by SOF2.5 release.
