Subject: alsa: Sigmatel stac92hd71b7 low HP volume
From: Klaas De Craemer <klaasdc@xxxxxxxxx>
Fix an issue on Dell E6500 notebooks with the Sigmatel stac92hd71b7 codec.
In the default snd-hda-intel configuration, the sound going to the
headphone jack goes comes directly from the DAC, resulting in very low
volume output. The patch changes the codec's widget connections so that
the internal mixer is put in between and sets its input amplifiers to the
maximum value. The output to the internal speaker port has been left
untouched. I have tested this and it gives a much better output.
