This ASUS D640SA desktop whose mother board is D640MB has
- two jacks which are a headphone and a mic on the front panel,
- three jacks which are a mic, a line out and a line in on the rear panel
- one internal speaker.
If I plug a headphone to the front headphone jack, there will be sound through the headphone jack, and no sound through the internal speaker. If I unplug the headphone from the the headphone jack, there will be sound through the internal speaker. And always no sound through rear line out, when I plug a headphone or an externel speaker to the rear line out jack.
Besides, I had checked and toggled the Auto-Mute Mode in alsamixer, but the rear line out still was not working. Then I checked the sound settings in GUI, and found there was no "Line Out" could be chosen, only the "Headphones" and "HDMI/DisplayPort". However, system does know that there is an "Intel PCH Line Out".

Consequently, I checked the pin widgets' default configuration values:
Node 0x14 [Pin Complex] wcaps 0x40058d: Stereo Amp-Out Pin Default 0x01014010: [Jack] Line Out at Ext Rear
Node 0x1b [Pin Complex] wcaps 0x40058f: Stereo Amp-In Amp-Out Pin Default 0x02214030: [Jack] HP Out at Ext Front
Because the headphone jack (Node ID:0x1b) locates on the desktop's front panel, not rear panel, I change the headphone jack's configuration from primary chassis to separate chassis. So, the configuration value of Node ID:0x1b should be 0x22214030.
This is OK, but...
Additionally, I toggle the Auto-Mute Mode of Realtek codecs to “Speaker Only” which makes signal outputs through line out jack when the "Line Out" is chosen in the sound settings.
... this is a matter of taste, and I don't think it good to set a different default from others. You can change it once and save it via alsactl.
The default state of Auto-Mute Mode of Realtek codec on this machine is "Line Out + Speaker". This disallows to output audio signal through the line out jack, even I already choose the "Line Out" as the audio output device in the sound settings. It means there is no way to use the line out jack in "Line Out + Speaker" state of Auto-Mute Mode on this machine.
It's a setup issue by PA, and it's not specific to this device at all. If PA wants the independent output, it can change to auto-mute off by itself.
To enhance the user experience, especially the new one who first uses Linux, changing this machine's Auto-Mute Mode to "Speaker Only" state, which allows to output the audio signal through the line out jack, will be the better choice.
By the way, if the "Headphones" is chosen as the audio output device in the sound settings, the audio signal will not output through the line out jack automatically.
Therefore, I think this part of the quirk is still needed on this machine.
Again, this isn't about the machine configuration, but a generic PA problem. Fixing it in a device-specific fixup is no right way.
Thanks for the hint which is about the PulseAudio. I will try to figure out the fix for the Auto-Mute problem with PulseAudio first. And the pin configuration fixup may be not need or still needed, after the try.
