Excuse me for dropping CC..
I set the direction bit to 0 and used get_gpio_data and get only: value =
0x0
also checking "IO[0-7] data=0-1" value in /proc/asound/card0/codec#0 shows
no changes at all when insert audio jack.
I tried also booting with "acpi=off". I tried older kernels from few years
ago. Nothing helps.
I wonder if there is some tool for Windows that I use to debug and see what
is sent to the codec so i replicate in Linux with hda-verb?
What am I doing wrong ? Is the below script correct for testing the GPIOs ?
for x in range(0,256):
mhex=("0x%0.2X" % x)
os.system("hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK "+mhex)
os.system("hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIRECTION "+mhex)
os.system("hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA "+mhex)
I think its not correct gpio_direction i guess could be only 0 or 1?
What happens when I pass a different value to data than 0/1 ? this should
also not be correct.
I guess 0x01 is the NID value is it okay to use 0x01 only or I have to pass
other values to it also ?
