I have to reread 4DWave datasheet. 4DWave was one of the best audio controller in its sound quality and wavetable support. FreeBSD's 4DWave support was very minimal(e.g. no wavetable support, using sound blaster mode for recording etc) so I wanted to implement missing features in the past but had no time to try it. As time goes, ariff also changed/enhanced a lot of sound framework so my understanding to sound subsystem is now very limited and I guess I need more time to understand sound subsystem by reading every code of the subsystem.
