Hi Folks, I've solved the problem.
Luckily, before the kernel upgrade wrecked my machine, I'd backed up the /home directories. After a lot of grief, I managed to install 15.10 from a flash drive (initially, the UEFI BIOS wouldn't let me boot from the CD or the flash drive). Changing the kernel from 3.13.74 to 4.2.0 seems to have nailed the problem. I now have sound and HDMI output. Hope someone will close this bug report, as it doesn't seem to be an option for me.. Thanks for all the help from you guys.
