Bochs/bochs/iodev/sound/soundosx.cc
Volker Ruppert fe49c73a6b Some work on the lowlevel sound support. 
- Define new structure bx_pcm_param_t and use it as a parameter for the method
  sendwavepacket(). The method startwavepacket() is now called from
  sendwavepacket() in case of a parameter change (temporary solution).
- soundsdl: Replaced waveready() call by some more accurate code for buffer
            space check in sendwavepacket().
- soundsdl: Moved code for reading from audio buffer to a new function.
- soundsdl: Temporarily increase the audio buffer size.
- Preparing the SB16 code for the OPL emulation port from DOSBox.
