The internal speakers and microphone don't work starting with the 5.3 linux kernel out of the box, until PulseAudio is updated. See #Audio.

Sleep/Suspend

S3 suspend will work out-of-the-box as long as Intel microcode is loaded.

Touchpad

On kernel 5.3 and lower, the touchpad will stop working after waking from suspend. THis can be fixed by reloading the i2c_hid kernel module on wakeup.

Graphics

As long as xf86-video-intel and xf86-video-amdgpu are installed, PRIME will work with the default configuration. The GPU will automatically power off completely when not in use.

All video outputs (HDMI, USB-C) are connected directly to the Intel UHD 620 Graphics.

Intel GVT-g is compatible with this laptop.

Audio

Note: The 4-channel audio and microphone work out-of-the-box as of 5.6.14-arch1-1 using SOF Firmware and the latest git version of PulseAudio (version 13.99, soon-to-be released as 14). You can install that version using pulseaudio-git^AUR). For the released version of PulseAudio (13 and older), please use the indications below.

To get it working with PulseAudio 13 and older, follow those steps:

1. Install sof-firmware (tested with 1.4.2-1)

2. Configure PulseAudio's to load Alsa modules with the correct device and channel settings, by adding these two lines to /etc/pulse/default.pa:

/etc/pulse/default.pa

...
load-module module-alsa-sink device=hw:0,0 channels=4
load-module module-alsa-source device=hw:0,6 channels=4

Note that Alsa card numbers can change when adding more audio devices (like, connecting a USB headset or a docking station). To ensure that index '0' always maps to internal audio, add snd slots=snd_soc_skl_hda_dsp to your module loading options.

3. Reboot, then use alsamixer to increase the "master" channel level of the sof-hda-dsp sound card (use the F6 key to switch cards). If you do not see sof-hda-dsp in alsamixer, you may need to add blacklist snd_hda_intel and blacklist snd_soc_skl to /etc/modprobe.d/blacklist.conf and reboot again.

4. If the output sounds tinny, try muting the "speaker" item in alsamixer.

Additional hardware

The laptop contains an M.2-2242 B-key slot, designated for the LTE modem. Alternatively, one could install an additional SATA SSD.
