this look like driver bug

Hint Strings
~~~~~~~~~~~~
The codec parser have several switches and adjustment knobs for
matching better with the actual codec or device behavior.  Many of
them can be adjusted dynamically via "hints" strings as mentioned in
the section above.  For example, by passing `jack_detect = no` string
via sysfs or a patch file, you can disable the jack detection, thus
the codec parser will skip the features like auto-mute or mic
auto-switch.  As a boolean value, either `yes`, `no`, `true`, `false`,
`1` or `0` can be passed.

The generic parser supports the following hints:

- jack_detect (bool): specify whether the jack detection is available
  at all on this machine; default true


- trigger_sense (bool): indicates that the jack detection needs the
  explicit call of AC_VERB_SET_PIN_SENSE verb


- auto_mute (bool): enable/disable the headphone auto-mute feature;
  default true







use early patching and hint 

try hint one by one to find out the cause 

disable power saving 

1) do not execute AC_VERB_SET_PIN_SENSE  (709) before AC_VERB_GET_PIN_SENSE
(F09)

trigger_sense=0


2) disable jack sense of headphone pin

set bit 8 of pin default of headphone pin complex


3) disable jack detect of all pins

jack_detect=0
