181 SDL$<name>$AudioBuffer - set to number of samples to buffer
182 in advance. Will default to a minimum of 1024 or twice
183 amount requested by program whichever is largest.
184 If not specified default is amount for 10 csecs.
185 Time that will be pre-buffered can be calculated as
186 sample to buffer * 1000 / freq milliseconds.
