You might have to change audio routing using sysctls or device hints,
see below for examples I use on my laptop (different model, so it's
more about the general idea)

Keep speakers and headphone jack separate (two separate audio devices):
cat >>/boot/device.hints <<EOF
hint.hdaa.1.nid26.config="as=2"
hint.hdaa.1.nid33.config="as=3"
EOF


Use headphone jack like most people do (recommended):
cat >>/boot/device.hints <<EOF
hint.hdaa.1.nid20.config="as=3 seq=0"
hint.hdaa.1.nid26.config="as=2 seq=14"
hint.hdaa.1.nid25.config="as=2 seq=15"
hint.hdaa.1.nid33.config="as=3 seq=15"
EOF

Maybe you could send the the output of sysctl -a | grep hdaa?
