From 6b45214277bec2193ad3ccb8d7aa6100b5a0f1a9 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 14 Oct 2011 15:26:20 +0200 Subject: [PATCH] ALSA: hda - Fix ADC input-amp handling for Cx20549 codec It seems that Conexant CX20549 chip handle only a single input-amp even though the audio-input widget has multiple sources. This has been never clear, and I implemented in the current way based on the debug information I got at the early time -- the device reacts individual input-amp values for different sources. This is true for another Conexant codec, but it's not applied to CX20549 actually. This patch changes the auto-parser code to handle a single input-amp per audio-in widget for CX20549. After applying this, you'll see only a single "Capture" volume control instead of separate "Mic" or "Line" captures when the device is set up to use a single ADC. We haven't tested 20551 and 20561 codecs yet. If these show the similar behavior like 20549, they need to set spec->single_adc_amp=1, too.
