I have the same problem: I want sound by headphone and beeps by beeper,
but disabling CONFIG_SND_HDA_INPUT_BEEP saved me.
well, intel HDA has a concept of routing sound sources through a number
of components and mixers to certain colored jacks.
you might search OUR FAVOURITE SEARCH-ENGINE for "/sys/class/sound/
user_pin_configs", and please report back any findings regarding the
format to use given a users preferred routing!
I have only:
$ egrep -Hi . /sys/class/sound/hwC0D0/*pin_conf*

but the files:
/sys/class/sound/hwC0D0/driver_pin_configs
/sys/class/sound/hwC0D0/init_pin_configs
/sys/class/sound/hwC0D0/user_pin_configs
are also present. "init_pin_configs" are set by the BIOS at startup.
maybe there should be _much more_ documentation available as to what to
put into user_pin_configs, but a little is there. look into[1] or the
equivalent path into your kernel docs:
"
For example, when you want to change the pin default configuration
value of the pin widget 0x14 to 0x9993013f, and let the driver
re-configure based on that state, run like below:
------------------------------------------------------------------------
# echo 0x14 0x9993013f > /sys/class/sound/hwC0D0/user_pin_configs
# echo 1 > /sys/class/sound/hwC0D0/reconfig
------------------------------------------------------------------------
