This is a note to let you know that I have just added a patch titled ALSA: hda - Fix silent output on Toshiba Satellite L40 to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 8064c6bec0774743034005ba8f7029fc81c642b0 Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai@suse.de> Date: Tue, 4 Feb 2014 07:39:06 +0100 Subject: ALSA: hda - Fix silent output on Toshiba Satellite L40 commit 4528eb19b00d9ccd65ded6f8201eec704267edd8 upstream. Toshiba Satellite L40 with AD1986A codec requires the EAPD of NID 0x1b to be constantly on, otherwise the output doesn't work. Unlike most of other AD1986A machines, EAPD is correctly implemented in HD-audio manner (that is, bit set = amp on), so we need to clear the inv_eapd flag in the fixup, too.
