Sound System Rework: Phase 1

Browse Source 
. Fixed Sample Rate for DSP
  (Now if your CPU is capable to run game at 100%, you will get pure sound without buzz or static noise)

. Fixed Sample Rate for AI
  (Now if your CPU is capable to run game at 100%, you will get sync'ed video and audio)

. Fixed Backend list for DSPLLE

. Improved Aduio DMA a bit
  (There might be a completely redesign in following phases)

WARNING: The whole rework will take time to complete.
This commit is compilable, but could be unstable.
So you can try it and test it but don't take it as a release rev!
