I recently opened a bug against GNOME Shell, because it was constantly displaying the headset icon even when I don't have a headset plugged in: https://bugzilla.gnome.org/show_bug.cgi?id=694680 After investigation, it turns out that PulseAudio always reports that I have a headset plugged in: https://bugzilla.gnome.org/show_bug.cgi?id=694680#c2 https://bugzilla.gnome.org/show_bug.cgi?id=694680#c3 What more information can I provide for debugging this?
Please attach the output of alsa-info when 1. headphones are plugged in and, 2. when they're not. Also the output of pactl list.

if BIOS setup one of the headphone jack as Line Out Node 0x0f the driver still need to enable unsolicited event for jack detection when it retasked Line Out as Headphone /sys/class/sound/hwC0D2/init_pin_configs: 0x0a 0x0221101f 0x0b 0x40f000f1 0x0c 0x90a79130 0x0d 0x90170110 0x0e 0x02813050 0x0f 0x02011020 0x10 0x40f000f2 0x11 0x40f000f3 0x12 0x40f000f4 0x13 0x40f000f7 0x14 0x40f000f5 0x21 0x934470a0 0x22 0x40f000f6 /sys/class/sound/hwC0D2/driver_pin_configs: 0x0c 0x90a79130 0x0f 0x0227011f 0x0e 0x02a79130 Node 0x0a [Pin Complex] wcaps 0x400181: Stereo Pincap 0x0000173f: IN OUT HP Detect Trigger ImpSense Vref caps: HIZ 50 GRD 80 Pin Default 0x0221101f: [Jack] HP Out at Ext Front Conn = 1/8, Color = Black DefAssociation = 0x1, Sequence = 0xf Pin-ctls: 0xc0: OUT HP VREF_HIZ Unsolicited: tag=01, enabled=1 Connection: 2 0x02* 0x03 Node 0x0f [Pin Complex] wcaps 0x400181: Stereo Pincap 0x00001737: IN OUT Detect Trigger ImpSense Vref caps: HIZ 50 GRD 80 Pin Default 0x02011020: [Jack] Line Out at Ext Front Conn = 1/8, Color = Black DefAssociation = 0x2, Sequence = 0x0 Pin-ctls: 0x40: OUT VREF_HIZ Unsolicited: tag=00, enabled=0 Connection: 1 0x05
Looking at your alsa info, there is no control called "Headphone Jack", or similar. Given the rewrite of the HDA driver in Linux 3.9, I also find it likely that your issue will be fixed if you upgrade to a newer kernel. Anyway, it's a kernel issue rather than a PulseAudio issue.
> I also find it likely that your issue will be fixed if you upgrade to a newer kernel. Indeed, I haven't seen this bug in so long I had completely forgotten about it. It definitely was fixed by an update, sorry I never came back to close this bug. Thanks.
