    I seek explanation for a strange behavior: as my codec dump can testify, I have speakers on pin 0x14 and HP on 0x15 (and, possibly, ext MIC at 0x18 and int MIC at 0x19), then why does the command

    sudo hda-verb /dev/snd/hwC0D0 0x18 SET_PIN_WIDGET_CONTROL 0

    mute my machine and

    sudo hda-verb /dev/snd/hwC0D0 0x18 SET_PIN_WIDGET_CONTROL 1

    restore sound?
