So, the last question.
Is it possible to write an application totally using ALSA user and 
kernel things (i.e., without having OSS emulation layer)?

In that case, if application will not open /dev/dsp then what ll it do ? 
Just pointers will be great for me.

And will it be possible to implement full-featured application which 
plays stereo and also provides equalizer and etc just by using ALSA ?
