Hey there! 
Yesterday I tried to get audio from my second monitor into Kubuntu through the line-in stereo jack which is now basically working after fiddling with "alsamixer" (un-mute Line & getting volume settings right) and adding "load-module module-loopback" to my "/etc/pulse/default.pa"
My current and biggest problem with this setup is the crackling sound / noise I get while playing audio - even after adjusting the line-in volume to ~5% (everything above that is just painful) and increasing volume on my external amplifier. (Under Windows 10 I have no crackling / sound problems with this setup)
What I've tried so far:
1) Having "load-module module-udev-detect tsched=0" (adding the "tsched=0")
in /etc/pulse/default.pa for deactivating timer-based scheduling in PulseAudio which helped other people with crackling sound.
2) Combining 1) with modifications in /etc/pulse/daemon.conf for setting the default fragment number and buffer size in PulseAudio (like here: https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Static_noise_when_using_headphones)
3) Explicitly writing the loopback source & sink with its rate and channels:
And 4) modifying /etc/modprobe.d/alsa-base.conf with "options snd-hda-intel position_fix=1" or "options snd-hda-intel position_fix=2" which was suggested here: [https://wiki.ubuntu.com/Audio/PositionReporting][2]
My system:

---
My basic audio setup:
Inputs:
- audio coming from second monitor into computer line-in
- all other audio is coming from the system / applications / music
Output:
- USB-DAC/AMP which my headphone is connected to
---
I hope you can help or give me some pointers to where I could find an answer
Thank you for your time and have a nice week!
