sound output connector reverts to headphones on boot

[hangfirew8]

On each boot, System Settings->Sound->(Output Tab)->Connector comes up as Headphones. Sound does not work until changed to Speakers. Setting holds through suspend but not a reboot. On each cold boot, setting reverts to Headphones.

I expect a setting of Speakers to hold through a reboot, so my system will have working sound on boot-up.

do you mean headphone jack detect kcontrol is incorrect or

pulseaudio select speaker port when headphone is unavailable ?

control.33 {
  iface CARD
  name 'Headphone Jack'
  value true
  comment {
   access read
   type BOOLEAN
   count 1
  }
 }

Ports:
  analog-output-speaker: Speakers (priority: 10000, not available)
  analog-output-headphones: Headphones (priority: 9000, available)
 Active Port: analog-output-speaker
 Formats:
  pcm

Raymond,

I'm sorry, I don't understand your question, or how to find the answer, or where your control.33 or Ports: comes from.

Both "Headphones" and "Speakers" choices are always available.

I'm running Gnome 3. The path to the visual control was given in the initial post. It always reverts to Headphones on boot. I get no sound from the laptop speakers. I change it to "Speakers"

The value should be false when you unplugged

amixer -c0 contents

 numid=33,iface=CARD,name='Headphone Jack',index=0
 ; type=BOOLEAN,access=r-------,values=1
 : values=off

[Raymond (superquad-vortex2)]

do you mean "headphone jack" kcontrol did not report the jack state when automute is disabled ?

Simple mixer control 'Auto-Mute Mode',0
  Capabilities: enum
  Items: 'Disabled' 'Enabled'
  Item0: 'Disabled'

[hangfirew8 (hangfirew8-netscape)]

I still don't understand. I never "unplugged." I do not use headphones or earbuds. I use only the laptop speakers.

It is reboot that causes the value to toggle, and the speakers to be disabled. This behavior started with the recent upgrade to 12.04.

Here is the current value of 33 from amixer -c0 contents:

$ amixer -c0 contents
numid=33,iface=CARD,name='Headphone Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=on

I just tried plugging and unplugging earbuds into the headphone jack (had to find it first) several times. There is no change in the amixer output for 33.

[hangfirew8 (hangfirew8-netscape)]

Automute is disabled in alsamixer. Here is the 18 portion of the output:

numid=18,iface=MIXER,name='Auto-Mute Mode'
  ; type=ENUMERATED,access=rw------,values=1,items=2
  ; Item #0 'Disabled'
  ; Item #1 'Enabled'
  : values=0

do you mean there are two bugs ?

1) headphone jack kcontrol always return true even when there is no headphone plugged

2) speaker still muted even auto mute is disabled

you have to send email to alsa devel mailing list

[hangfirew8 (hangfirew8-netscape)]

e-mail sent.

I installed ppa ppa:diwic/ppa but package snd-hda-tools won't install, probably because it's not built for Precise Pangolin. Without snd-hda-tools, I can't get to the hda_codec needed to run the python script.
