[HP Pavilion dv7 Notebook PC, IDT 92HD75B3X5, Internal] Speakers not disabled when headphone jack plugged in

Hmm, I'm unduplicating due to the last comment:

"David: These are labelled with a headphone on my laptop (see h20424.www2.hp.com/program/cnb/kr/ko/resources/dv7-new-brochure.pdf) It has the same headphone symbol as on page 3. Page 4 clearly labels it as having 2 headphone jacks and 1 microphone jack."

According to your BIOS, these are the jacks you have:

Node 0x0b: [Jack] Mic at Ext Front
Node 0x0f: [Jack] Line Out at Ext Front
Node 0x1e: [Jack] SPDIF Out at Ext Front
...and internal mic and speakers.

I'm wondering if you really have two headphone jacks, maybe one of them is digital out / spdif only?

I can get audio using either of the two headphone jack connectors (middle and right connectors) in my headphones (ordinary in-ear headphones). A google search on S/PDIF mentions that some laptops have a combined S/PDIF and headphone connector socket, which is likely to be one of the jacks on the front panel.

With alsamixer:
   Speaker -- effects the internal built-in speaker volume
   Front -- effects the volume of the headphone jacks
   Master -- effects both Speaker and Front volume

So for me, alsa/alsamixer are applying the volume correctly. Also, the jack detection was working with Ubuntu before the switch to pulseaudio, and worked on the Vista setup that came with the machine.

I will try the suggested fix on the other defect to see if that works for me as well.

Applying the change to /usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf to ignore the Front element actually works better for me than what I had before, although it does not work correctly:

With headphones plugged in, I hear audio through the headphones (not through headphones and speakers).

With headphones unplugged, I don't hear anything (speakers are not playing anything).

Muting then unmuting the audio through the Sound Settings dialog mutes and unmutes the speakers only.

The Jack stuff is interesting - I wonder if these two headphone jacks actually is connected to the same pin perhaps? Could you install snd-hda-tools from https://launchpad.net/~diwic/+archive/ppa/+build/2768994/+files/snd-hda-tools_0.20110516%7Eoneiric1_amd64.deb
and then run "sudo hda-jack-sense-test -a" - with different jacks plugged and unplugged (e g try both headphone jacks independently) you should be able to figure out with node number belongs to which jack.

Left = Mic ; Mid = Headphone ; Right = Headphone

0. With nothing connected to the front:

1. With a connection on the Right (mic):

2. With a connection to the Middle jack (headphones):

3. With a connection to the Right (headphone):

$ sudo hda-jack-sense-test -a
Sigmatel specific "Power-Map: 0x00" verb ignored for the moment
Sigmatel specific "Analog Loopback: 0x00" verb ignored for the moment

Pin 0x14 (Not connected): present = No
Pin 0x18 (Internal Mic): present = No
Pin 0x19 (Not connected): present = No
Pin 0x1e (Black SPDIF Out): present = No
Pin 0x1f (Not connected): present = No
Pin 0x20 (Not connected): present = No

NOTE: I don't have a S/PDIF cable/connector to try the S/PDIF output.

So ...

Pin 0x0b (Black Mic): present = left jack/connector on the front
Pin 0x0f (Green Line Out): present = middle *and* right jack/connector on the front

Sorry, 1 should read Left (mic)!

Status changed to 'Confirmed' because the bug affects multiple users.

Ok, so from the software's standpoint, the two jacks are one and the same.

Any workarounds?

Bug 877954 is awaiting SRU. That would explain why speakers are not unmuted on unplug.

Workaround:
Edit /usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf

Change [Element Front] and [Element Speaker]
;switch = mute
;volume = merge
switch = ignore
volume = ignore

you can then use alsamixer for the levels of Speaker / Headphone
Pulseaudio affects Master and PCM.
execute "killall pulseaudio" to reload config
