/************* PCM DMA buffer sizes *******************/

/* If you are using high playback or recording speeds, the default buffersize
   is too small. DSP_BUFFSIZE must be 64k or less.

   A rule of thumb is 64k for PAS16, 32k for PAS+, 16k for SB Pro and
   4k for SB.

   If you change the DSP_BUFFSIZE, don't modify this file.
   Use the make config command instead. Seems to allow only 4K, 16K,
   32K, 64K.
