      ALSA: hda - Fix ADC input-amp handling for Cx20549 codec · 6b452142
      Takashi Iwai 提交于
      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.

      ALSA: hda - Keep EAPD turned on for old Conexant chips · 254f2968
      Takashi Iwai 提交于
      In the old Conexant chips (5045, 5047, 5051 and 5066), a single EAPD
      may handle both headphone and speaker outputs while it's assigned only
      to one of them.  Turning off dynamically leads to the unexpected silent
      output in such a configuration with the auto-mute function.
      
      Since it's difficult to know how the EAPD is handled in the actual h/w
      implementation, better to keep EAPD on while running for such codecs.
