I recommend to use for this Pipewire. On pulseaudio not tested this method.

Add new file

sudo subl /etc/wireplumber/wireplumber.conf.d/50-bluez.conf

With

monitor.bluez.properties = {
    bluez5.enable-msbc = true
}

Then

systemctl --user restart pipewire pipewire-pulse wireplumber

sudo systemctl restart bluetooth

TLDR

I wondered for two weeks why the method described in the official Arch Linux guide, using the WirePlumber configuration file at /etc/wireplumber/bluetooth.lua.d/51-bluez-config.lua and syntax like bluez_monitor.properties = { It doesnt’work

Instead, use /etc/wireplumber/wireplumber.conf.d/50-bluez.conf and syntax described in the beggining of post and will be fine

Plasma 6.0.1 is too laggy

That is guide how to downgrade:

sudo nano /etc/pacman.conf

#[core]
#Include = /etc/pacman.d/mirrorlist


#[extra]
#Include = /etc/pacman.d/mirrorlist

[core]
SigLevel = PackageRequired
Server=https://archive.archlinux.org/repos/2024/03/01/$repo/os/$arch

[extra]
SigLevel = PackageRequired
Server=https://archive.archlinux.org/repos/2024/03/01/$repo/os/$arch

Then

sudo pacman -Syyuu

If you have a problem with broken u need to downgrade each package manually with pacman -U.

 sudo pacman -Qi expat libelf lib32-expat lib32-libelf
 sudo pacman -U /var/cache/pacman/pkg/lib32-expat-2.6.0-1-x86_64.pkg.tar.zst
 sudo pacman -U /var/cache/pacman/pkg/lib32-libelf-0.190-1-x86_64.pkg.tar.zst

If you have problem with plasma-framework5 exists in filesystem

 sudo pacman -Syyuu  --overwrite '*'

The final step

sudo reboot

1. Openrc is sux because mpd and etc. Resolving by systemctl
2. After upgrade - Chrome update problem in build
3. After upgrade syslog-ng failing on boot

apt install xpra xvfb

git clone https://github.com/kaueraal/run_scaled.git

cd run_scaled/
cp run_scaled /usr/local/bin
chmod +x /usr/local/bin

run_scaled <yourapp>

install

sudo apt install zsh 

make default shell zsh:

chsh -s $(which zsh)

oh my zsh:

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

copy plugins similar:

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

all plugins enum:

plugins=(git zsh-autosuggestions zsh-syntax-highlighting fast-syntax-highlighting)

hardcode install powerlevel10k:

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

Set ZSH_THEME="powerlevel10k/powerlevel10k" in ~/.zshrc
