I tried alsamixer with interesting results. I used f3 [playback]. I first unmuted everything and tried to raise the volume of all. I could raise the volume of all but the first headphone column The columns from left to right are Master Headphone Headphone Headphone Speaker PCM Auto-Mute et al ^^^^ | could not raise this column When the headphone is plugged in the second column is set to un-mute and the speaker column is set to mute. When the headphone is unplugged the reverse occurs. All this looks right. But I can't raise the volume setting for the second column (I can and did raise columns 3 and 4. I sure looks like the headphone gets unmuted but is permanently at volume 0. Also the gnome volume control (top bar) shows headphone and when I move its slider it raises/lowers the first column (master) volume. To answer Alec's questions this is a 3.5mm jack. Nothing new in dmesg. sudo lspci | grep -i audio shows 00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09) 00:1b.0 Audio device: Intel Corporation Wildcat Point-LP High Definition Audio Controller (rev 03) I think/hope we are getting close and thank everyone for their help. allan
