This is a note to let you know that I have just added a patch titled ALSA: hda - Apply click noise workaround for Thinkpads generically to the linux-4.2.y-queue branch of the 4.2.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-4.2.y-queue This patch is scheduled to be released in version 4.2.8-ckt2. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 4.2.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ---8<------------------------------------------------------------ From 9c3782e5f4b963fa93e18169447475828d786055 Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai@suse.de> Date: Thu, 10 Dec 2015 23:30:43 +0100 Subject: ALSA: hda - Apply click noise workaround for Thinkpads generically commit 157f0b7f6c0cc0bc88647390006e959e267a0143 upstream. It seems that a workaround for Thinkpad T440s crackling noise can be applied generically to all Thinkpad models: namely, disabling the default alc269 shutup callback. This patch moves it to the existing alc_fixup_tpt440_dock() while also replacing the rest code with another existing alc_fixup_disable_aamix(). It resulted in a good code reduction.
