I have downgraded to 5.70-1.1, which does not have this problem. -- System Information: Debian Release: trixie/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.6.9-amd64 (SMP w/12 CPU threads; PREEMPT) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages bluez depends on: ii dbus [default-dbus-system-bus] 1.14.10-3+b1 ii init-system-helpers 1.66 ii kmod 31-1 ii libasound2 1.2.10-3 ii libc6 2.37-13 ii libdbus-1-3 1.14.10-3+b1 ii libdw1 0.190-1+b1 ii libglib2.0-0 2.78.3-1 ii libreadline8 8.2-3 ii libudev1 255.2-3 ii udev 255.2-3 bluez recommends no packages.
