sound blaster library: for 32-bit builds change goldplay_dma[] to DMA
allocation buffer, change code to use that allocation buffer, so that
goldplay mode can work correctly (better than the previous hack of
pointing DMA directly at the goldplay_dma[] member of the struct which
would fail if the struct ended up above 16MB).
add code to configure reading the DSP status N times after sending
command in Direct DAC output mode, to see if that helps prime the SB16
DSP through completing the command.
