VirtualBox - 5.0 Host - Windows 10 64bit Guest - Windows 10 64bit

Did the upgrade from 8.1 using CD which worked okay except that I lost all sounds. I'm using Windows Direct Sound - Intel HD Audio, and the driver is High Definition Audio Device version 10.0.1024.16384 (now there's an ominous set of numbers).
Is anyone else having this problem, and does anyone know how I can resolve this issue?

Thank you

Yes,

This is a known issue. I was in the IRC chat room and was informed that this issue is known and will be resolved in the next update. I am currently running the latest test release and it does not have the fix yet, so sit tight. Issue resolution is on the way as per the IRC folks.

Thank you.

In the meantime you can try this workaround - https://www.virtualbox.org/ticket/14361#comment:12
