But the feature is still available. It can be enabled via sysfs "hints". For example, # echo "loopback = yes" > /sys/class/sound/hwC0D0/hints # echo 1 > /sys/class/sound/hwC0D0/reconfig will take the mixer elements back. Also, hp_detect and gpio-bits can be changed similarly on the fly. If you find any problems with this change, please let me know. thanks, Takashi
