I'd been trying Linux on and off over the last 5 years ago with a spare
Z20t I have and thought I'd put in some recent findings that might help
with this issue.
Z20t-B and z20t-C models seem affected the same, with Ubuntu and Arch
based installs - also tried various kernels from 5 through to 6.7.

** Description changed:
On initial boot, sound on internal speakers is working. After standby it
doesn work anymore, but a analog headset does. Switching around in
pavucontrol doesn't work... Internal microphone works.
I'm using Ubuntu 16.04 64 bit on a 4.4.0-34-generic kernel.
Only workaround is to not use suspend to ram, but suspend to disk.

It's a pity - it's a great laptop apart from this problem, but not being
able to shut the lid without losing sound is a significant drawback. It
wouldn't be so bad if there were a workaround of some sort, but I've not
seen one and I don't know how to go about looking for one.

I, the original reporter, can confirm that this problem persists with
current BIOS and Ubuntu.

Thank you for the reply.
Are you saying that you need confirmation from the original bug reporter
(Michael) that his problem still exists with the latest BIOS and latest
Ubuntu, and that confirmation from other people won't do because we
might have a different problem?
I can understand the
apsaras, it's helpful for developers if folks report their own bug so logs may
be obtained from the hardware, regardless of similarities, via a terminal:
ubuntu-bug linux
Please feel free to subscribe me to it.
To do otherwise risks issues being ignored as unconfirmable noise.

You received
penalvch: in view of the fact that we have independently confirmed the
bug with the latest BIOS and the latest Ubuntu, would it now make sense
to change the status back to Confirmed (and remove the bios-outdated
tag)?
Also, can I ask why you changed the importance down to Low? Having sound
not
Can confirm the problem still exists with Ubuntu 19.10, all up-to-date.
Where can I dig to debug?
Thanks!

I have the same problem with a Z20T-C (Z20T-C-11H m7-6y75).
I am using Ubuntu 18.04.3 (kernel 5.0.0-32-generic).
I updated to BIOS 6.30, but unfortunately this didn't make any
difference.
