@mmifas,
Thank you for your testing result, and It looks like the headphone (0x21) can't detect the plug/unplug. I have no idea why this happened.
I already asked for help from Realtek technical expert, he suggested we turn on the hidden register (0x20), then generate an alsa-info.txt.
To do so, please follow the steps as below:
1. sudo echo 1 > /sys/modules/snd_hda_codec/parameters/dump_coef
2. generate a new alsa-info.txt and upload it to launchpad. (refer to #14).
Thanks.
