Why did you add additional comments to the fixed-released bug? It's not within my intension to mention about the bug. I think your behaviour is unwelcome to developers. You should have used button of 'This bug affects you' or something similar...

I'm not sure what the point of your lecture was/is. But thank you for initially pointing me to the bug-report where my "inappropriate" comments got this bug correctly resolved. Furthermore, hopefully this means people updating to 16.04LTS in the near future will still have use of their Envy24 sound cards.  The end result is that the problem was acknowledged, a new build was done, and the issue was resolved.

Well, if you improve something you use, it's better to follow each rules of development.

In your case, at first, you should watch release schedule of Ubuntu 16.04.
https://wiki.ubuntu.com/XenialXerus/ReleaseSchedule

You can see date of KernelFreeze is Apr. 7th 2016. In my opinion, till then, what you're expected is:
 - Read wiki page about Ubuntu kernel development cycle and understand it
  - https://wiki.ubuntu.com/Kernel
 - Test with daily build image
  - http://cdimages.ubuntu.com/daily-live/current/
 - When you still find your bug, seek it in launchpad.net
  - https://launchpad.net/bugs
 - When you find similar bug, watch it by subscibing or something like it.
 - When you cannot find similar bugs, register it as new one.
  - but you should keep more days to investigate duplicated bug

At least, additional comments without enough consideration seems not to be helpful to yourself, against your expectation. And you should not test with packages in PPA. PPA is just Private Package Archive. The packages in PPA do not always go for official release.

Although I said some lectures, I wish this bug will be fixed in Ubuntu 16.04 release.

Instead of wishing, I'd rather make things happen and get things fixed.
