From 527e4d73af16dfc35a770dfdc3874ef63c359ea6 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 27 Oct 2011 16:33:27 +0200 Subject: ALSA: hda/realtek - Fix missing volume controls with ALC260 ALC260 has multiple mixer widgets connected to the shared DAC, but the driver currently doesn't check this possibility and ignores when the DAC is shared with others. This resulted in the silent output from some routes because of lack of the amp setup. This patch adds the workaround for it by checking the route even with the shared DAC, but also checking the conflict with the existing control for the very same widget NID.
