Various ASoC board/card drivers use a components string to communicate to userspace which output (speakers / headphones) and input (internal mic / headset mic) routes have been setup by the card driver so that the UCM profiles can dynamically adjust to this.

ATM it is sort of hard to figure out what the component string has actually been set to by the kernel. Log the components string set on the snd_soc_card to help with UCM profile development.
