Actually, the use of built-in speaker and headphones at the same time happens
only if I boot with headphones plugged in; and the way to mute the speakers but
not the headphones is simply to unplug and reinsert the headphones. So that's
fine. (It's different from what I'm used to, but
output.

I'm attaching the dmseg output.

I thought I noticed the same, so it wasn't just me. I installed TLP
looking at these pieces of advice:

... and perhaps it's helped. Or it just settled to normal. Right now, fans
are reasonably calm.

@Corbin:
Hi Corbin, can I ask what that separate bug is? Since we seem to have the same
kind of machine...

Title:
Kernel
On 5.5.10, sound is also not working; but just as on 5.4.0-40, at least
when I click on volume control (in panel), it does show me a volume
level and allow me to open audio mixer, which shows "Dummy output" and
"No cards available for configuration." (So there seems to be some
change somewhere
Sound seems to be working fully on 5.6.0-050600rc3.
On 5.5.19-050519, sound was totally broken. When I clicked on volume control,
the message was "not connected to the pulse audio server."

Thanks, that worked!
And with this I can report that sound in 5.6.3 DOES work for me. Will
go back now and try to find the *1st* workable kernel.

@Hui Wang:
How do I actually load a mainline kernel?
I installed Ubuntu Mainline Kernel Installer, and used it too install kernel
5.6.3;
but at boot attempt, I get this message:
error: /boot/vmlinuz-5.6.3-050603-generic has invalid signature.
error: you need to load the kernel first.

I did try 5.4.0-39 before, and it did have the same problem (= no
sound). I also tried 5.4.0-37, and I think also 5.4.0-33. I'm a bit
too tired now to install those kernels again and run dmesg, but can do
it tomorrow, if it helps.

OK, think I got it. I'm adding apport file apport.linux.yukw0jij.apport as an
attachment.
Keep in mind that after installing Mint 20 Xfce with kernel 5.4.0-26, and
updating to 5.4.0-40.44, I did two things that changed what I get from the
sound system, one for the better, the other for the

@Hui Wang: where can I find guidance on how to upload the logs? You
need those 18 that Corbin posted in comment #1? Where would I find the
scripts/commands that generate them?

I have the same problem on a Lenovo Ideapad 5 (15IIL05), with Linux Mint
20 Xfce installed: sound works fully (incl. mic) on 5.4.0-26, but not at
all on 5.4.0-40. For reference, I've had a discussion on the Mint
