Audio/HDA:

  • Lowered timer to 100Hz and start/stop it only if needed. Should improve overall performance.
  • More work on dynamic stream assignments (SDI/SDO select) by the guest -- should make more Linux guests compatible with HDA.
  • 屬性 svn:eol-style 設為 native
  • 屬性 svn:keywords 設為 Author Date Id Revision
