Video playback freezes in Linux guests with KVM paravirtualization enabled

Description
When KVM paravirtualization is enabled in VirtualBox 5.0.0 Linux guest operating systems fail to playback video. This is apparent with all video tested, including web video using Flash or HTML5. This has been tested on Antergos, Mint 17.2, and Fedora 22. Host Operating systems used to confirm this bug were Windows 8.1 and Windows 10.

I disabled the audio in the settings for the virtual machine and video seems to play fine. This issue may be related to the virtual audio interface.

I have found that using the Null audio driver for my host is the ultimate fix. This is likely not a bug and can be discarded.

Well, it could be a problem with the VBox audio backend. Any change with VBox 5.0.2? If you still experience these freezes, could you attach a VBox.log file from a 5.0.2 session?

No response, closing. Before you consider to re-open, please try the latest 5.0.x version (currently 5.0.14).

Hi, I have exactly the described Problem with Virtualbox 5.1.6 (latest update). Host is Windows 7, Guest is Arch Linux. Setting Audio to Null Audio Driver, Videos can be played back. Using "Windows DirectSound" it seems like the video is playing, but only a still image is visible.
On a Gentoo Guest (where for some reason, I cannot get hardware acceleration to work) this problem never occurred.
To clarify, it seems that the issue is not related to paravirtualization. 3D acceleration does not seem to affect video playback either. Videos will begin to play or show a few frames but will then freeze.
