Bug 106771

BIOS doesn't seem to pass the proper pin configuration for your headphone jack.
You have to figure out by yourself, e.g. via hdajackretask or such utility, which pin corresponds to which actual I/O.

pulseaudio expect headphone jack must exist but yours seem have line out jack

try

hdajacksensetest -c1 -a

with headphone plug and unplug

do it mean driver does not support line out and speakerconfig since there is no auto mute control ?

I have 3 jacks. One is line out, one is mic and one is spdif. When setting options snd-hda-intel model=asus-mode5 I can use the line out as a headphone jack, but no other jacks work. 

I searched for hdajacksensetest and it appears it is packaged with snd-hda-tools but I can't find an actual current source. The repository I found returns error 404

http://git.alsa-project.org/?p=alsa-tools.git;a=tree;f=hdajacksensetest;hb=HEAD

it also need sysfs-pin-configs.c

can you confirm that node 0x16 is the headphone jack ?

the driver does not put headphone and line out mic jacks at same location to support multi channel

I'm not sure how to get any information running the hdajacksensetest command as shown. It simply returns command not found. However I can run ./hdajacksensetest but it only returns output for HDMI and I can find no manual, --help, or Readme. If helpful, hmdi output is:
Pin 0x05 ( Digital Out, HDMI): present = No
Pin 0x06 ( Digital Out, HDMI): present = No
Pin 0x07 ( Digital Out, HDMI): present = No

I am not sure how to confirm what node is for the headphone jack but hdajackretask shows "Internal SPDIF Out" Pin ID 0x1e

./hdajacksensetest -c1 -a

try to find out whether node 0x16 report present=yes when HP plug and present=no when HP unplug

use hdajackretask to overwrite the unconnected pin node 0x16 to HP

Set as boot default and reboot

as the driver does not put HP and Line Out of same location (Ext Front) for multichannel output

HP jack can auto mute Line Out and Internal speakers

you have to retask the HP jack to Line Out and Mic jack to line out for surround 5.1

your line out,speaker and subwoofer already used three audio output

three playback volume controls have to be shared between four output pins and mio pin

I had tried running ./hdajacksensetest -c1 -a but it returns: Option parsing failed: Cannot parse integer value '-a' for -c. 

I had previously tried hdajackretask but I ran into issues getting it to function properly. You can see a run down of troubleshooting steps I took on this post here: http://ubuntuforums.org/showthread.php?t=2300693&p=13381269#post13381269 that links to instances I found

So I tried again with hdajackretask and selected "Advanced override" then set  unconnected pin node 0x16 to HP and clicked Apply now and it worked! I'm not sure why ticking the Advanced override box makes a difference but it is now working.

you have to post output of alsa-info.sh after you retask HP

seem only line out jack support EAPD

subwoofer need bass speaker playck volume control

do the subwoofer use left, right or both channels since your mic jack can be retask to support center/lfe?

I hear Rear Right and Rear Left.

your internal speaker and subeoofer are connected to same audio output after you added the headphone pins

itis a bug of driver in support 4 channels based on the number of speaker pins

fix max channel which depend on number of unique DAC instead of number of speaker pins

Hi!

The issue with the heaphone jack not working seems to be related to the BIOS not reporting pin 0x16 as a headphone jack.

We have commited a patch to fix this that will hopefully reach the 4.20 kernel.
http://mailman.alsa-project.org/pipermail/alsa-devel/2018-October/140818.html

This issue seems similar to this one:
https://bugzilla.kernel.org/show_bug.cgi?id=190681

Thank you!
