[PATCH] ALSA: hda/realtek: Enable audio line out on ASUS D640SA

From: Jian-Hong Pan
Date: Mon Apr 02 2018 - 05:57:45 EST


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".

[ 10.104494] input: HDA Intel PCH Front Headphone as
/devices/pci0000:00/0000:00:1f.3/sound/card0/input13

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.
Additionally, I toggle the Auto-Mute Mode of Realtek codecs to âSpeaker
Onlyâ which makes signal outputs through line out jack when the "Line
Out" is chosen in the sound settings.
