Ok lets look at it :
sh_audio->a_buffer_len == buffer length in bytes
sh_audio->o_bps == bytes/sec of the data in the buffer.
So sh_audio->a_buffer_len/sh_audio->o_bps == length of the buffer in sec.
1 usec == 1/1000000 sec so 
sh_audio->a_buffer_len/sh_audio->o_bps*1000000 == length of the buffer in usec.
Sorry for this VERY BIG math mistake, I'll commit this.
