Had a similar problem with Lenovo S740 (Ubuntu 18.04, 19.10 and 20.04). Tried different combinations in alsa-base.conf, hda-jack-retask - nothing worked.

And then surprisingly this thread helped (see https://gist.github.com/hamidzr/dd81e429dc86f4327ded7a2030e7d7d9#gistcomment-3315737 ).

What I've done is I appended next two lines to /etc/pulse/default.pa:

# /etc/pulse/default.pa
load-module module-alsa-sink device=hw:0,0 channels=2 # note that I used 2 here
load-module module-alsa-source device=hw:0,6 channels=2
```

For those of you having problems in Ubuntu 20.04 with Realtek ALC285 this could be a solution.
