	 Intel ASoC Machine Drivers. If you have a Intel machine that
	 has an audio controller with a DSP and I2S or DMIC port, then

	help
	  Some drivers report the I/O configuration to userspace through the
	  soundcard's long card name in the control user space AP. An unfortunate
	  side effect is that this long name may also be used by the GUI,
	  confusing users with information they don't need.
	  This option prevents the long name from being modified, and the I/O
	  configuration will be provided through a different component interface.
	  Select Y if userspace like UCM (Use Case Manager) uses the component
	  interface.
	  If unsure select N.
