This is my first attempt at using the open source driver.

The system is a fresh install of Ubuntu 16.04.2 LTS.

uname -a

4.4.0-72-generic

sudo lspci -vvvnn | grep --after-context=28 7160

I've followed the instructions at https://github.com/ljalves/linux_media/wiki/Installating. The build completes successfully. However I receive the following error when I attempt to load the module:

modprobe: FATAL: Module saa716x_budget not found in directory /lib/modules/4.4.0-72-generic

Is anybody able to help please ?

Linux kernel 4.6 is needed for this driver.

Upgrade to the HWE kernel (currently 4.8) in ubuntu and rebuild:

sudo apt-get update
sudo apt-get install --install-recommends linux-generic-hwe-16.04

Also see: https://github.com/ljalves/linux_media/issues/150 https://wiki.ubuntu.com/Kernel/RollingLTSEnablementStack
