One thing you haven't noticed yet is that your internal microphone doesn't work. That's one of the things the new driver fixes. Come Mint 20 this summer, all should be good.
Here's what gave it away for me. From the dmesg output there was this line:
Code: Select all
[ 4.841313] snd_hda_intel 0000:00:1f.3: Digital mics found on Skylake+ platform, aborting probe
That stopped the "legacy" snd-hda-intel driver from loading. That's the driver most of us have been using for many years. The new sof-audio-pci driver is what everyone will be on eventually, but it's quite a change that needs a number of other updates done as well (firmware, topology and config files) that the Bionic version of Ubuntu will never see.
Back on this now;
1) The Grub argument that was added, simply disables the detection of the mic?
2) Does this mean that with this sound output fix, we won't have the input working until the summer, when the sof-audio-pci rolls out?
(yes, I would prefer to be able to have both output and input working, and reloading alsa modules doesn't help)
thank you for helping me understand
EDIT: Applied the fix on viewtopic.php?p=1709728#p1709728
and now Mic is recognised, but still not working. I tried pavucontrol to make it work, but now the output has the issue of being only 0% or 100%...
EDIT2: Tried also this solution
found online, but it breaks sound, and even ends up with a system not able to shutdown.
EDIT3: Tried again only adding the
Code: Select all
options snd-hda-intel model=laptop-amic
On board mic not working, on board sound is only at 0 or 100%, but at least with external devices on the audiojack, they seem to work well, both output and input (tested with arecord and aplay as suggested)
I could pick up that thread for debugging the mic with blacklisting the intel snd.
