You made a lot of updates to this record and I cannot tell whether or not you hit on issues that requires coding changes on the Ubuntu Audio side.
I did want to report that I seem to have found a resolution that I am satisfied with. To summarize, I mentioned that after backing off from Virtual Box 5.0.2 and installing Virtual Box 4.3.30, my audio problems were resolved and I was able to use the Volume Slider in order to control the Volume. After contacting the Virtual Box team, they gave me a customization option change to correct the video problems I was experiencing that did not relate to this audio problem. Since that customization option solved the video problem, I wanted to go back and reinstall VBox 5.0.2 to see if the Audio problems persist. Short answer is No, they did not exist under a fresh install of 5.0.2. I speculated to the VBox team that I perceive the Maintenance upgrade from VBox 5.0.0 to 5.0.2 did not work completely correct. The fact that I performed a full uninstall of VBox going to the older 4.3 level and to the current 5.0 levels both had the audio working correctly. I can only assume the service upgrade process was the cause. Please close this record as resolved at your earliest convenience.
