on every reboot or shutdown my Laptop beeps very loud (Dell E6230). This behaviour came up after the installation of Bookworm. I tried all stuff I found. Blacklisting of pcspkr kernel module, on my system I can't find a module like pcspkr or similar. Tried to find the hex code 0x07 in the binary of /sbin/shutdown. As suggested in forum.debian.de.All that had no effect.
Do you get a beep if you run systemctl reboot --no-wall ?It's possibly related to https://github.com/systemd/systemd/commit/cdf370626f08ed509a5dde9d5618eed29d625032
In that case, wall messages do trigger a beep on your system. If you don't want that, you can blacklist pcspkr.
