Adding the following patch generates a crash with alsaucm
alsaucm -c sof-soundwire set _verb HiFi set _enadev Headphones alsaucm: conf.c:4355: snd_config_iterator_first: Assertion `config->type == SND_CONFIG_TYPE_COMPOUND' failed. Aborted (core dumped)

I am not sure if anyone ever used the SectionModifier, if it's a bug in alsa-lib or alsaucm.
SectionModifiers are part of the current proposal in PipeWire according to the documentation for "stream endpoints". https://docs.pipewire.org/page_objects_design.html
"The available UCM modifiers for each UCM device will be added as streams, plus one "default" stream for accessing the device with no modifiers."
Thanks. It was a bug. Fixed in ea5481296f281625ef6517208ebf6e41b5fd838c .
