I did the following:
// dir = 0, data = 1
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x08
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x00
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x08
// dir = 0, data = 0
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x08
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x00
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x00
// dir = 1, data = 0
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x08
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x08
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x00
// dir = 1, data = 1
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x08
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x08
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x08
Repeat these for each GPIO pin, from 0 to 7.
I set the last parameter from 0x01, 0x02, 0x04, 0x08, ... 0x40, 0x80
while having something paying in the background - still no sound.
