why is MME playing much better than ASIO4ALL

I have a 64 bit acer Aspire R7 with 8GB RAM and runing windows 8.1. i have bin using adobe audition(now using CS6) for about 10 years now and i have never found myself havin this problem:

1)It so happens that my MME drivers are giving less glitches than the ASIO4ALL.(no matter how much i play around with the buffer size)

2)when using the asio4all during play back,the volume is lower compared to that of the MME drivers.

3)the asio4all icon on the system tray keeps flickering from play(green) to an exclamation mark(red) constantly

i cant use my MME for my projects coz i gat quite a bunch of plugins waiting to join the party...hence it will start glitching too sooner than later(((pliz help!!!help help help!!!!
