From 4528eb19b00d9ccd65ded6f8201eec704267edd8 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 4 Feb 2014 07:39:06 +0100 Subject: [PATCH] ALSA: hda - Fix silent output on Toshiba Satellite L40 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.
