In a previous post, I showed how to get sound on an ubuntu Hyper-VM build but it was pretty complicated.
I came across a simpler method using ffmpeg
scientificprogrammer.net
Basic steps are as follows:
1) install xrdp so you can get enhanced mode.
I used this for ubuntu
www.nakivo.com
2) install pulseaudio
3) install ffmpeg on Windows - I chose ffmpeg-N-103679-g7bbad32d5a-win64-gpl (see 1st link for details)
4) run this in powershell with admin rights
It runs and jumps to a cmd file and sort of stops dead as it executes - that is how it works.
With a little effort, you could auto start this using Task Scheduler I am sure. I just created a .bat file. This needs to be run each time you start windows (if you intend to use Linux with sound)
5) install ffmpeg on ubuntu vm
6) Setup link to pulse audio
7) Start audio
Note: Change IP address for IP address of your Linux VM. Mine is 192.168.1.198. Look in network settings in Linux VM.
8) Kick start process
Sometimes you need to kick start process by running following command.
It takes a few seconds to kick in.
You have to repeat steps 6 and 7 (and 8 if applicable) each time you restart Linux. Guys cleverer than me will work out how to create a batch file to do this on start I am sure.
You get a slight time delay but you can correct this in VLC. Again, guys cleverer than me will work out how to have a permanent delay (+ or -) with ffmpeg.

Getting audio working on Ubuntu VM on Hyper-V - Scientific Programmer
As the author of NetCoreAudio, a .NET library that is designed to play audio on Windows, Mac OS, and Linux, I need to have all three operating systems available for testing. The simplest and cheapest way to set up multiple operating systems is to use virtual machines (VMs). My main Continue Reading
