  Log:
  "Workaround for sound lag in current snd_emu10kx driver. Real problem
   is interaction between in-kernel sound buffer handling and hardware.
   With small buffer, there are times when both harwdare reads and
   kernel writes to the same buffer (it is only visible on slow machines, i
   think). I'm digging in channel.c and buffer.c to find a solution that
   allow use of large hardware buffers without sound lags - hardware can
   handle buffers up to 32Mb."
