Thanks for quick response. Well, I myself am writing Audio Player 
application for some embedded device.
I generally used to write open("/dev/dsp") device and then do read/write 
of RAW data on that device and it used to work till now.
I was/am doing so and completely unaware of OSS/ALSA.

But then when I found while rebuilding kernel that there are two sound 
sub-system OSS and ALSA.
ALSA is a new one and OSS is deprecated. And so I thought to remove 
everything about OSS from Kernel.

So, I guess my application is such that it wont work with ALSA-only-kernel.
But then on contrary, I think that opening a /dev/dsp and throwing data 
is a simple way AND what is so wrong in that and why ALSA-only-kernel 
cant understand that ?
