Tested - the RT722 no longer appears under /sys/bus/soundwire/devices/. Will send as patch 1/2 in v2. > Can you check if c8f3c9fa75ff ("ASoC: soc-acpi / SOF: Add best_effort > flag to get_function_tplg_files op ") is in your kernel? > In theory, it will skip the BT link and will load other function > topologies. It is in my tree (7.2.0-rc7), but best_effort is only ever set from the topology name: topology.c: bool no_fallback =3D strstr(file, "dummy"); With a real sof_tplg_filename it is false, so sof_sdw_get_tplg_files() returns 0 at SSP2-BT instead of skipping it, and the card fails to probe. The comment above that line describes 'dummy' as meaning no monolithic fallback exists, which is the case here - so I think it is the intended mechanism, though this would be the first machine entry to use it. Happy to do it differently if you prefer. Thanks, Sataporn
