The same regression hits Intel SOF/HDA: on a ThinkPad E16 Gen3 (Arrow Lake, Core Ultra 7 255H, Conexant SN6140) no internal card is registered on v7.4-rc2, with skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: Failed to add route ... Analog Playback and Capture: fail to add hda routes, ret -19 This also looks like the regression reported for Meteor Lake here: https://lore.kernel.org/all/mAZY9HZuXAXUf7zv8tqXquMtquf7iW2CIZB7WhU-SnwWp-Rpr0e8yixTsb3lAeQsO64PwwWlOao8aMjQ4hTKOQ6grCiNmaWZmFRXMdPICD8=@proton.me/ With this patch on top of v7.4-rc2 the card is registered again: the topology loads, and speaker, mics and HDMI outputs are back, with no warnings in the log.
