Sorry for this email bombardment, but I just booted back to stock F15
kernel (2.6.38.8-32.fc15.x86_64) and noticed that speaker and headphone
controls actually do what they advertise. Still, it is impossible to
make the sound go through the speakers when headphones are plugged in (I
tried pavucontrol for this). The converse might be true though - if you
select "analog headphones" in pavucontrols the speakers go silent.
