Yes, it was one reason why I used 'sound/' as root of the ALSA tree. The 
second reason was to move old OSS tree to new directory to make less 
confusion. And the third reason was to just keep ALSA directory same as in 
our local development tree (which is out-of-kernel tree - containing only 
ALSA parts).

I feel that from the maintenance perspective, having one directory is a 
plus. We have already 'drivers/usb/core', 'mmc/core', 'drivers/base' (ALSA 
toplevel and midlevel modules use functions from this tree) etc.

If we have general consensus that sound drivers should go to back to
'drivers/sound' then I would move all code. We can move 'sound/core' tree 
to '/sound' in next round later...
