Lenovo Thinkpad 300e Gen2 Debian failing to restore audio

[brightresurgence]

Describe the bug A clear and concise description of what the bug is.

This script used to work without a hitch, but I recently had to reinstall my OS so I'm in a predicament here. The kernel installation popup no longer appears and when the script "completes" nothing happens anymore.

Boardname If you don't know where to find this, run cat /sys/class/dmi/id/product_name Octopus Logs Generate logs with wget https://raw.githubusercontent.com/chrultrabook/linux-tools/main/debugging.sh; bash debugging.sh and attach the output here.

#!/usr/bin/env bash printf 'Welcome.\nThis script will ask you for sudo password, which is necessary to extract required information.\n'

Get current username before escalating permissions

user=$USER

Get board name

board="$(cat /sys/class/dmi/id/product_name)"

Get current date and time

date="$(date +"%Y-%m-%d_%Hh%Mm")"

Specify where to store logs

logdir="debug-logs-$board-$date" logarchive="debug-logs-$board-$date.tar.gz"

Create directory to store logs

mkdir -p $logdir cd $logdir

Download cbmem and mark it as executable

wget https://mrchromebox.tech/files/util/cbmem.tar.gz &> /dev/null tar -xf cbmem.tar.gz rm cbmem.tar.gz chmod +x cbmem

(Dumb question but am I meant to have pipewire installed?)

[brightresurgence]

Just a thought now but am I meant to use the chultrabook kernel instead of the standard one?

[brightresurgence]

Alright so I'm manually downloading the chultrabook kernel files so I'm hoping that it should do the job this time, so I guess the problem is mostly in regards to the kernel failing to install itself automatically.

[WeirdTreeThing]

I remember someone saying the prebuilt kernel artifact expired. I guess it's that time once again to rebuild it. The problem is no chrultrabook maintainers really use debian so we kinda just forget about the kernel existing.

[brightresurgence]

Would you recommend switching to another OS? I could probably go to Endeavour or something, im just partial to debian because it's what I'm used to.

[WeirdTreeThing]

Even using debian trixie would be better. But in general using a non-LTS distro is better for chromebooks where you need up-to-date software to have everything working properly.

[brightresurgence]

whats an LTS distro again and how would Trixie help?

[nothingneko]

LTS distros like Debian, Ubuntu LTS, and the EL family hold back package updates for stability

If you wanna stay in the Debian ecosystem, Trixie like Tree mentioned, or Ubuntu interim releases are a good choice

[brightresurgence]

A few times I've installed something like ani-cli on the Trixie/Sid and it literally marks my entire KDE environment as well as network-manager for autoremoval. I've lost a few installs of Debian this way.

Is this a common thing? And are there any other threats of the sorts if I use the Trixie repo?

[brightresurgence]

oh yeah P.S having manually installed the chultrabook kernel, everything works INCLUDING the cros-keyboard-map thingy tree made. That was also busted before I got the kernel in order.
