blockSize dosn't work?

Is there a problems with the block size?

This dosn't make any sound:

(

o = Server.local.options;

o.blockSize_( 4410 );

s.boot;

)

{ SinOsc.ar(440, 0, 0.1) }.play(s);

when boot the message is:

SC_AudioDriver: sample rate = 44100.000000, driver's block size = 512

Thanks
