YouTube clips on Hyper-V machines

Error occurred on Windows 7 Hyper-V guest on a Windows 8.1 Host.

If you attempt to play a YouTube video on a direct connection to a Hyper-V virtual machine instance an error will occur:

"An error occurred please try again later"

Vague?!

The suggested list of thing to try is predictably unhelpful.

The problem appears to occur because Hyper-V virtual machines do not have any virtualised sound hardware.

Using a RDP connection to the guest unexpectedly enabled the video to play because the sound was configured in the RDP client to "Play on this computer"
