Could you check whether it hits with the latest kernel (4.13.x), too?
Just to be sure.
Comment 2 Takashi Iwai 2017-11-08 10:59:33 UTC 
And please try the patch below.  It's from Realtek for the potential fix.

Bug is still happening with 4.13.11 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13.11/

I will try to patch and build a kernel this week-end and let you know.
