Yes, but you seen to have missed my first comment.  Here again:

I'd like to move this into sound/core.
Also, the kconfig name appears a bit too lengthy to me.
================================================================

And, after reading this again, I wonder whether we just take the
existing CONFIG_EXPERT for allowing the selection of more knobs like
CONFIG_SND_PROC_FS.  

SND_PROC_FS
	bool "Sound proc file" if EXPERT
	depends on PROC_FS
	....
