Hi everybody,
if you have GPD Pocket with ubuntu-mate 18.04.3 on it and your microphone won't work and right speaker is off, open as administrator /usr/share/alsa/ucm/chtrt5645/HiFi.conf and replace text with new one from: https://fedorapeople.org/~jwrdegoede/chtrt5645/HiFi.conf and restart your GPD. Works like a charm.
To quit annoying constant spin of fan while on AC, open: /etc/default/grub and add to line 11, GRUB_CMDLINE_LINUX=“gpd-pocket-fan.speed_on_ac=0” , update grub and voila....
