OSx 10.11.6 sound plays in slow motion

Post by Moordoom »

My guest is hosted on an Intel i7-2600k (8 Cores) 3.4Ghz with 32GB of RAM , and SSDs for hard drives running Windows 10 Pro.
Running VirtualBox 5.1.22r.
I have OS X 10.11.6 setup and running, with the guest having 16GB of RAM, 4 CPUs, and the Default set for Acceleration.
The Audio driver is Windows Direct Sound, and the audio controller is Intel HD Audio.

When I play a sound (wav, mp3, etc) it takes few seconds for it to start up and is playing in slow motion.
When I play a video (youtube, etc) it plays the video at normal speed (visually), but the sound is out of sync and in slow motion.

Do I need to disable something on the host machine (anti-virus, malware protector, etc) to fix this issue, or am I missing or have an incorrect setting in the guest's settings?
CentOS 7.1 and Ubuntu 15.10, sound and video work fine.
Any sound setting other than Windows Direct Sound, and Intel HD Audio, and I get no sound.
