[silverblade] 34242: Implemented sound library routines for obtaining Sound Blaster DSP chip version, speaker on/off and DSP 4.xx sample rate configuration. Renamed functions to shorter names. Updated test code in sb16_nt4. DSP version is reported as 4.05 in VirtualBox - which seems to report invalid speaker status... Finally, updated e-mail address.
