Hello Raymond, I followed through on your question from the kernel bug report page here. I figure, best to leave the Kernel people alone until it is proven that it is a Kernel issue. Being that I was lost on how to apply the patch that you posted the URL for; I had to do a bit of research on how to apply this a52 patch. This is what I found on this issue with some insite on applying the patch.

Now with the asound.conf copied to the /etc folder from the XBMC folder this has changed things a bit.

I have had no issues with earlier versions of Ubuntu from 10.x, 12.04 LTS and 13.04. Even the original distro which was originally on this HTPC, Susse. I have researched all avenues for a remedy to my issue including #ALSA, #Pulseaudio and #Ubuntu IRCs. Some have mention it is possibly a kernel issue. I do have audio via S/PDIF which is stereo only. I did not upgrade the existing version; which most would, I have done a clean install of Ubuntu 13.10. Everything is working fine except for my audio issues. HDMI output is not showing in either ALSA or Pavucontrol. On the previous versions of Ubuntu I had many options of Digital 5.1 surround ouputs including HDMI. All that is available now for surround sound is analog options. In the Sound configuration panel I only have Digital Output (S/PDIF)Built-in Audio and Analog Output Built-in Audio which are only Stereo, HDMI is now missing in 13.10 I have tried so many apparent fixes in various forums which included editing confg files, uninstalling and reinstalling Alsa-base and Pulseaudio. I am surprised that I have any sound out of the S/PDIF Coax or Optical now. Thank you for taking the time to look this over. I am not 100% sure this is a bug , but by all the research, suggestions on the IRCs and not having this issue on previous versions, I am leaning towards it being a bug. If you need any further information please let me know and I will respond asap.
