Lots of questions, I'll attempt to answer as best as I can. First. Host OS Level: uname -a Linux gwsux79 3.13.0-62-generic #102-Ubuntu SMP Tue Aug 11 14:29:36 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Second, Sound Card/Sound Support: I don't understand the question about "Real Sound Card Support 5.1". Onboard Audio Intel Motherboard DX79SI The following URL is documentation for the Motherboard. https://downloadmirror.intel.com/20560/eng/DX79SI_TechProdSpec06.pdf Third question asks Which Audio Backend is being used for VirtualBox 5.0? I take the the defaults(Audio) for installing any Guest OSes. When I look at the Settings for the guest I reported this issue, it lists Host Driver: PulseAudio Controller: ICH AC97 I hope this answers your questions.
