pulseaudio -k && pulseaudio -vvvv 2>&1 | tee pulseaudio.log

When using pulseaudio, everything works normal as expected - aside from the fact that plasma/kde5 isn't able to save the default output device in its system settings -.

Music can be played. If the jack is then unplugged from the Line Out port and reattached again, the Port Line Out is no longer available as a port that can be selected, neither via pavucontrol nor any other means that i know of.

To get the port back, pulseaudio has to be killed, i.e. pulseaudio -k. Afterwards it will work again until the jack is removed and everything begins again.

I forgot to mention, this problem appeared when switching from pulseaudio 7.0 to 8.0. Also i tried it before, when plasma and kde was on the version before the one i'm currently using: plasma-5.5.5 kde-frameworks-5.21 kde-applications-15.12.3.

Downgrading to pulseaudio 7.0 solved the problem then.

Comment 4 Raymond 2016-05-27 08:56:49 UTC

as your three detectable jacks (HDMI, headphone and Line Out) are unplugged, the digital port (SPDIF) become the only port

Comment 5 f1ght3r 2016-05-27 08:58:50 UTC

I unplugged only the green one, standard Line Out, and plugged it back in 2 seconds later. Doesn't matter what kind of device was connected. The logs were cut after the jack had been plugged in for at least 5 seconds.

Afterwards I've found no way to get sound working again via that Line Out port other than killing pulseaudio.

your five analog audio output node 0x2, 0x03, 0x4, 0x5 ,0x25 and two digital digital output 0x6 and 0x10 are playing concurrently ( Converter: stream=5, channel=0)  when you turn on

Comment 7 f1ght3r 2016-05-27 09:16:59 UTC

I'm sorry I can't be more help, but I don't know enough about alsa and pulseaudio. I just know one thing: After the jack has been removed and plugged in again, there is nothing i can do to get music to come out of the device plugged into that slot!

Should I have configured something somewhere that I don't know of, please tell me which configuration files to remove, so I can try to start from default.

Comment 8 Raymond 2016-05-27 09:23:48 UTC

as you turn on "IEC958 default PCM", the digital audio output have same stream tag 5 as those analog audio output

"as you turn on "IEC958 default PCM", the digital audio output have same stream tag 5 as those analog audio output"

I didn't turn anything on or off, i just played music, unplugged Line out to switch from my stereo to headphones (plugged back in) and no music anymore, no port Line Out available anymore.

I just don't understand what I am supposed to do. Please tell me in simple sentences what I need to do to resolve this issue.

You're probably suffering from this bug:
https://bugs.freedesktop.org/show_bug.cgi?id=93903

This will be fixed in 9.0. In the mean time, you can switch from the digital profile back to analog in pavucontrol's "Configuration" tab. I understand that's very annoying, if this has to be done often, and maybe not any less inconvenient than running "pulseaudio -k".

Added a new mixer switch to enable/disable the sharing of the default
PCM stream with analog and SPDIF outputs.  When "IEC958 Default PCM"
switch is on, the PCM stream is routed both to analog and SPDIF outputs.

in theory, the driver have to stop the analog/ digital pcm stream before it start digital pcm sin the two digital audio output already playing and need to stop

the control should be protected similar to 'independent hp switch'

http://www.intel.com/content/www/us/en/support/boards-and-kits/desktop-boards/000007156.html

hda controller support multi streaming, no only headphone and line output play two different stream, you can also play different audio to analog and digital pcm

however the driver still not support playback for two digital audio output, it only treat one as primary and the other as secondary

Turning this switch off has a merit for some codecs, though.  Some codec
chips don't support 24bit formats for SPDIF but only for analog outputs.

Allow opening the dedicated SPDIF stream while running on analog dup
mode.  Then the SPDIF stream is once reset and assigned for the new
stream.  It's useful for exclusive SPDIF output like AC3/DTS.
