2018-01-19 03:55:32 -0600	commented answer	Crackling noise with XPS 13 9360 (i5-8260) Unfortunately I cannot unload a module that is in use. But maybe there is a possibility to (re-)set the parameter while the module is running. On the other hand, /sys/module/i915/parameters/ tells me that enable_guc_loading is still set after waking up.

2018-01-18 15:12:05 -0600	asked a question	Crackling noise with XPS 13 9360 (i5-8260) Original title: Kernel parameter not working after wake My Dell XPS 13 9360 (i5-8250U) exhibits noise/crackling. This happens on load or screen changes and can reliably be forced when playing a (muted) video. The Arch wiki suggests a kernel parameter to remedy the situation [1]: `i915.enable_guc_loading=1` This works directly after boot, until the first sleep/hibernate. After wakeup, the crackling is back until the next reboot, when the kernel parameter apparently takes effect again. I suppose that after wakeup and reinitialization of the i915 module the parameter is not being set? I am runnig Fedora 27, a quick test with an Ubuntu Live Disc showed the same behaviour, so I guess this is not distro-specific but in fact a general driver problem. Any ideas how to fix this? update - solved Solved the problem using a kernel patch that extends a known workaround for this laptop's audio device [2]. I changed the original title as it was misleading. With the patch applied to kernel 4.14, the kernel-parameter mentioned above is no longer required. The patch should make it into kernel 4.14.15 and 4.15. [1] `https://wiki.archlinux.org/index.php/Dell_XPS_13_(9360)#Crackling_sound_with_screen_changes` [2] https://lkml.org/lkml/2018/1/22/169
