From c4394f5b807289c180a486df70c1a9b1f192f1cb Mon Sep 17 00:00:00 2001 From: Lydia Wang Date: Mon, 4 Jul 2011 16:54:15 +0800 Subject: [PATCH] ALSA: hda - Fix issue that front can't output sound for VT1718S For VT1718S, Mixer 9 doesn't expose the connection to DAC 0. So when building up a 'PCM Playback' amplifier control, it will fail since getting DAC 0 index of Mixer 9 returned -1. So I added a dac_mixer_idx to indicated the actual index of DAC 0 to Mixer 9. Following is the patch and next mail is another.
