I am in favor of keeping /sound around with the
non-hardware-dependent code, much like /block does with regard to

So that's /sound for PCM/mixer etc. and /drivers/sound with the
actual driver parts like cs46xx.

Just like:

PS. But then again, I could also imagine
	/block (core)
	/block/drivers (drivers)
	/net (core)
And the sound parts are already mostly there.
