Ticket #6026 (closed defect: fixed)
audio does not sync to video (audio lags behind) in XP guest on VB3.1.2 on Fedora 12 host

Playing any kind of video results in the audio noticeably lagging behind the video. This happens in all applications; youtube is a quick way to verify the problem.
Both video and audio are smooth, but the audio lags behind. Maybe there is some buffering between the guest and the host that causes a delay here?
This is a total killer for video editing, which is my main reason for using VirtualBox. It is not practical to edit videos under VB because I can't tell whether I'm producing properly synchronized video or not.
I am running a 32-bit XP guest on a Fedora 12 host. This is with VB3.1.2, but it has been a problem right back as far as I can remember (at least back to Fedora 9, and VB2.x). I don't know whether the same problem exists with other hosts and other guests.
