./scripts/twister -T samples/audio/sof/ -l

Gets a slew of errors like:

@nashif fyi.

Same as #31143

@nashif @galak we probably need a ifdef INTEL_CAVS_FAMILY around SOF atm as today it only builds against certain xtensa SoCs.
Fwiw, @lyakh is doing some updates to make the code fully generic in time for SOF 1.7 and Zephyr 2.5 (there are some drivers/arch code that is getting pulled to the SOF build in some places).
