It's not possible to have independent line out and headphone output
on
your hardware. There is only one analog device on your card.

The easy way to output same audio to both output is disable drivers
auto
mute mode and change pulseaudio conf files
Simple mixer control 'Auto-Mute Mode',0
Capabilities: enum
Items: 'Disabled' 'Enabled'
Item0: 'Enabled'

You have to ask Tiwai to enable independent hp for your realtek codec
on
desktop ( e.g. no internal mic and hda controller
support enough SDO)
You can specify hint indep_hp=1 by early patching, the driver
automatically disable automute when you switch on independent hp
switch
https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/Documentation/sound/alsa/HD-Audio-Controls.txt
Independent HP When this enum control is enabled, the headphone
output is
routed from an individual stream (the third PCM such as hw:0,2)
instead of
the primary stream
Okay, so following your advice I set up modprobe.d to specify the
early-patching files:
$ cat /etc/modprobe.d/snd_hda_intel.conf
options snd_hda_intel patch=onboard-patch,hdmi-patch
and specified the hint in /lib/firmware/onboard-patch:
$ cat /lib/firmware/onboard-patch
[codec]
0x10ec0892 0x1849d892 0
[hint]
indep_hp = 1
this seems to work fine, I can query the card hints and indep_hp shows
up:
$ cat /sys/class/sound/hwC0D0/hints
indep_hp = 1
but pulseaudio still only shows one sink. Do I need to manually load
another sink module?
