Changeset 60941 in vbox for trunk/src/VBox/Devices/Audio/AudioMixer.cpp

Message:

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.

File:

• trunk/src/VBox/Devices/Audio/AudioMixer.cpp (modified) (3 diffs)
