From 6ab42ff44864d26e8e498b8ac655d24ee389d267 Mon Sep 17 00:00:00 2001 From: Hui Wang Date: Mon, 15 Jun 2015 17:43:39 +0800 Subject: [PATCH] ALSA: hda - adding a DAC/pin preference map for a HP Envy TS machine On a HP Envy TouchSmart laptop, there are 2 speakers (main speaker and subwoofer speaker), 1 headphone and 2 DACs, without this fixup, the headphone will be assigned to a DAC and the 2 speakers will be assigned to another DAC, this assignment makes the surround-2.1 channels invalid. To fix it, here using a DAC/pin preference map to bind the main speaker to 1 DAC and the subwoofer speaker will be assigned to another DAC.
