The Pin Default values in the dump you posted seem to correspond to the default values in use when the sound level is so low (i.e. when the outputs are configured as line-out rather than speaker) ? To change this, per your second post, I apparently need to change default device bit 23-20 of Pin Default from speaker (1) to line out (0).
If I read the docs you linked correctly, then I should be able to use something like # echo 0x0C 0x01014020 > /sys/class/sound/hwC0D3/user_pin_configs # echo 1 > /sys/class/sound/hwC0D3/reconfig to experiment with changing those values and verify that it corrects the low sound problem ? I tried it like that - I needed to use a script it to kill pulseaudio, issue the commands and let pulseaudio respawn. That worked as I checked the user_pin_configs and they were set to 0x01014020 rather than 0x01114020 after the command. There was also an audible click from the speakers. But the sound volume is still low. What am I missing ?
