I am using the green Line Out. When I tested kernels, I started with my working 3.16.6-2.1-x86_64 kernel with sound fully configured and working. All I did was change the running kernel. Reboot. Log back in. Launch a Youtube video. Listen and observe framerate and behavior of my mouse as I moved it around. As I stated performance was affected resulting in slow video playback, stuttering mouse movement and loss of sound with exception of the one kernel which had sound but performed poorly. I made no other sound adjustments during the kernel tests.
