We have a Dell AIO, there is neither internal speaker nor internal mic, only a multi-function audio jack on it.
Users reported that after freshly installing the OS and plug a headset to the audio jack, the headset can't output sound. I reproduced this bug, at that moment, the Input Source is as below: Simple mixer control 'Input Source',0 Capabilities: cenum Items: 'Headphone Mic' 'Headset Mic' Item0: 'Headphone Mic'
That is because the patch_realtek will set this audio jack as mic_in mode if Input Source's value is hp_mic.
If it is not fresh installing, this issue will not happen since the systemd will run alsactl restore -f /var/lib/alsa/asound.state, this will set the 'Input Source' according to history value.
If there is internal speaker or internal mic, this issue will not happen since there is valid sink/source in the pulseaudio, the PA will set the 'Input Source' according to active_port.
To fix this issue, change the parser function to let the hs_mic be stored ahead of hp_mic.
