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 <a href="https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda/patch_realtek.c?id=1565cc358585be40608b46f18f7ac431a1aae2bc">https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda/patch_realtek.c?id=1565cc358585be40608b46f18f7ac431a1aae2bc</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
