    4. Plug headphones or speakers into the appropriate jack

    5. Unplug the device for subsequent tests.

[Sylvain Pineau (sylvain-pineau)]

The pactl parser fails to load the `pactl list` output. Could you please attach the output of this command. It will allow us to provide a fix for the new syntax.

[Jerry Kao (jerry.kao)]

@hao-sheng
please provide pactl list

[Hao-Sheng Lu (haosheng.lu)]

pactl list provided by Intel

[Sylvain Pineau (sylvain-pineau)]

the checkbox-support parser needs to take into account the optional ALSA UCM pretags [1]:

#define PA_UCM_PRE_TAG_OUTPUT "[Out] "
#define PA_UCM_PRE_TAG_INPUT "[In] "

[1] https://github.com/pulseaudio/pulseaudio/blob/master/src/modules/alsa/alsa-ucm.c#L55

The parser syntax for Port and PortWithProfile requires the following patch:

    __syntax__ = (
+ p.Optional('[Out] ').suppress()
+ + p.Optional('[In] ').suppress()
        + p.Word(p.alphanums + "-;").setResultsName('port-name')

[Betty Lin (bettyl)]

Install the custom 5.0.0 kernel in mantis dvt2 (201905-27066) and run "audio/speaker-headphone-plug-detection", the error message didn't occur but checkbox also didn't detect the headset was plugged in. (Headset OSD didn't pop-up too)

This issue should verify when the custom 5.0.0 kernel is in OEM image then.
