There's nothing at the driver level that would prevent the use of independent outputs, such as built-in speakers and HDMI concurrently. You can verify this assertion by opening different terminals and trying speaker-test -Dhw:0,0 -c2 -r48000 speaker-test -Dhw:0,3 -c2 -r48000 (use 0,7 8 9 10 as needed, depending on which device is tagged as connected to a valid HDMI output in the mixer 'Jack' status) I am not sure though how the Gnome settings would let you do this. This seems like a user-space problem to me?
