Debian on Thinkpad X13 AMD

Finally, a portable ThinkPad X-series with 32GiB of RAM.

Packages required: * amd64-microcode - CPU Microcode * firmware-iwlwifi - Intel WiFi * firmware-realtek - Realtek Ethernet * firmware-sof-signed - Audio

Enable Sleep -> AMD in the BIOS. To work around [this bug](https://gitlab.freedesktop.org/drm/amd/-/issues/1230).

In /etc/pulse/default.pa add an explicit load-module module-detect. module-udev-detect doesn't seem to do the right thing on its own.

The [Ubuntu bug](https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1901922) includes a patch to the volume level.
