briefly ubuntu 16.04.02 kernel 4.8.0-45-generic, it seems system detected audio hardware, but failed to add kernel module, when use modprobe to add module, it prints error, use dmesg show some symbol unknow, so does I install audio driver failed or wrong audio driver version? best regards

lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)

    You installed a wrong audio driver. The drivers are part of the kernel; try to restore or reinstall your kernel package. – CL. Apr 4 '17 at 12:33
