I upgraded from Ubuntu 16.04 w/ Samus kernel 4.4.2 and had two problems:
[SOLVED] Suspend will shut down
I followed the Arch Pixel instructions (sudo apt install acpi tpm2-tools and add modprobe conf) but no luck. Then, based on this bug report, I added GRUB_CMDLINE_LINUX_DEFAULT="quiet splash tpm_tis.force=1 tpm_tis.interrupts=0" to /etc/default/grub.cfg, ran grub-mkconfig -o /boot/grub/grub.cfg and it worked!
Constant noise when speaker is enabled
When the speaker channels are unmuted (via enable-speaker.sh script in this repo), I hear a constant white noise, which can't be muted and does not honor the master volume. The headphones work normally. If nothing else, it looks like a hardware failure, but the noise only appeared after I upgraded from Xubuntu 16.04 to 20.04, which is a bit too coincidental to not be a software issue.
Since then, I have tried installing several other dists (Mint, GalliumOS) and even recovered the original ChromeOS, but the problem persists and I have ran out of ideas.
