Hi,

I followed the steps in the dv6 bug report:
-----
Open
/usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf

Change:

[Element Front]
switch = mute
volume = merge
override-map.1 = all-front
override-map.2 = front-left,front-right

To:

[Element Front]
switch = ignore
volume = ignore

...and reboot to try the new settings.
-----

This means that:
  1/  pulseaudio no longer overrides my audio settings whenever the
computer reboots or when pulseaudio resets;
  2/  I need to explicitly use alsamixer to adjust the speaker and
headphone volume correctly.

This works for me as I have it configured for headphones all the time
(speaker volume at 0 and the headphone volume turned up) as I only
listen through headphones anyway.

According to the discussions on the bug, this is an issue with the
ALSA/kernel driver mis-detecting the jacks.

HTH,
- Reece
