That is the obvious thing to do. But alsamixer doesn't seem to have a separate slider for the headphones. Or else I just don't know how to find it. And when I use amixer to give me a list of the available ccontrols, I get: hendrik@notlookedfor:~$ amixer controls numid=4,iface=MIXER,name='Master Playback Switch' numid=3,iface=MIXER,name='Master Playback Volume' numid=2,iface=MIXER,name='Capture Switch' numid=1,iface=MIXER,name='Capture Volume' hendrik@notlookedfor:~$ There's nothing here to suggest there's a separate control for the headphones. Yet something is detecting the headphones, because the speakers shut off when I plug them in and trn on again when I unplug them. And the headphones themselves work fine on other devices, such as my ASUS TF101, an Android tablet. > I have this issue as well.
