## Firmware

In August of 2018 Lenovo has joined the Linux Vendor Firmware Service (LVFS) project, which enables firmware updates from within the OS. BIOS updates can be queried for and installed through fwupd.

## Fingerprint reader

See Lenovo ThinkPad T460p#Fingerprint reader; the T460p and X270 use fingerprint readers with the same issue. See also https://linux-hardware.org/?id=usb:138a-0097.

## No audio over HDMI

Use `aplay -l` to list all audio devices. Use speaker-test to find the correct device-id for HDMI audio, e.g.

    $ speaker-test -c 2 -r 48000 -D hw:0,7

Once you have identified the correct audio device id, add the device at the end of your `/etc/pulse/default.pa`:

    /etc/pulse/default.pa

    load-module module-alsa-sink device=hw:0,7 channels=2 rate=48000 sink_properties=device.description=HDMI

Finally:

    $ killall pulseaudio
    $ pulseaudio --check
