Last Update for tonight.

I understand it is monumentally difficult to support all of the varieties
of hardware that exist and because of that, I make myself available to test
or provide information for my specific operating environment.

For the most part, I expect that the OS packages that I install ask for
customary user input like names, passwords, and the like.
I do not expect to have to supply or know details about my specific
hardware other than gross features like memory allocations, number of
processors and similar things.

I have identified an Audio Problem that effects specific Ubuntu
Distributions currently under development and also identified related
distributions in the same Ubuntu Family that does not have this problem
with the same VirtualBox running on the same hardware platform.

Besides the Ubuntu distributions, I also run various other Linux
distributions, OpenSUSE, Linux Mint, Fedora, Oracle Linux, Windows 10
Technical Preview.
I have not experienced anything like this on any of the other Guest OSes
that I just listed

If you have additional information requests, I will be happy to try and
supply whatever you ask.
If you have possible workarounds or code solutions, I will happy to try
them .
If we need to get VirtualBox involved in debugging the problem, I will be
happy to work with their representatives.

Otherwise, I will track this issue and hope that some day it gets resolved.
