just in case you didn't noticed you already can set different setups for 
some periods (frags) and periodsizes. it would be triggered by the -abs 
option in mplayer. it isn't documented i know.

      switch (ao_data.buffersize)
    {
    case 1:
      alsa_fragcount = 16;
      chunk_size = 512;
        mp_msg(MSGT_AO,MSGL_V,"alsa-init: buffersize set manually to 
8192\n");
        mp_msg(MSGT_AO,MSGL_V,"alsa-init: chunksize set manually to 512\n");
      break;
    case 2:
      alsa_fragcount = 8;
      chunk_size = 1024;
        mp_msg(MSGT_AO,MSGL_V,"alsa-init: buffersize set manually to 
8192\n");
        mp_msg(MSGT_AO,MSGL_V,"alsa-init: chunksize set manually to 
1024\n");
      break;
    case 3:
      alsa_fragcount = 32;
      chunk_size = 512;
        mp_msg(MSGT_AO,MSGL_V,"alsa-init: buffersize set manually to 
16384\n");
        mp_msg(MSGT_AO,MSGL_V,"alsa-init: chunksize set manually to 512\n");
      break;
    case 4:
      alsa_fragcount = 16;
      chunk_size = 1024;
        mp_msg(MSGT_AO,MSGL_V,"alsa-init: buffersize set manually to 
16384\n");
        mp_msg(MSGT_AO,MSGL_V,"alsa-init: chunksize set manually to 
1024\n");
      break;
    default:
      alsa_fragcount = 16;
      if (ao_mmap)
        chunk_size = 512;
      else
        chunk_size = 1024;
      break;
    }
    }

fragcount is periods here and chunksize is periodsize (could be reanamed 
probably).

btw. could you send me your changes you made?
