ALSA: hda - Tweak OLPC XO-1.5 microphone bias
Our contacts at Conexant suggested that we reduce the external microphone bias to 50% in order to center the input signal with the DC input range of the codec. This is because the microphone port is DC coupled for potential use with sensors. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
