ubuntu releases new versions every 6 months (12.04 was released month 4 of 2012) so 12.04 is 18 months old - I also experienced sound issues on earlier releases - ubuntu 13.10 seems fine. You can always burn onto a CD/DVD a download of 13.10 to see of booting into ubuntu 13.10 from the CD gives you sound.

This can be rather annoying when you are working with a VM which dual boots either Ubuntu or Windows 7 as the guest OS.

Hyper-V/Ubuntu 12.04 sound not working. I have searched around the forums for a way to get sound working. However, the best I could find was that Ubuntu works well apart from the sound. Apparently this is a known problem and the Ubuntu community are waiting for Hyper-V to be fixed to allow sound?
