With the very latest alsa-driver, you can change the pin defcfg value
via sysfs. Grab the alsa-driver snapshot tarball below
ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz
Build it and install it. Then you'll have the files user_pin_configs
in /sys/class/sound/hwC0D* directory. Write the NID and the value
to this file as root.
# echo 0x21 0x1552150 > /sys/class/sound/hwC0D0/user_pin_configs
Then re-configure the setup by writing 1 to reconfig file there:
# echo 0x21 0x1552150 > /sys/class/sound/hwC0D0/reconfig
Run "alsactl restore" to restore the mixer status after that.
