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

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)
/net/drivers
/sound
/sound/drivers
And the sound parts are already mostly there.
