    Setup Belabox modified with Wireguard remote access, wireguard-multipath and BiB Comms audio output working via Pipewire, Pulse and ALSA

DO NOT RUN ON BELABOX: Flash belabox image to SD card (/dev/sdX):
sudo dd if=Downloads/belabox_rock_5b_plus-xxxxxxxx-xxxxxxx.img of=/dev/sdX bs=4M status=progress oflag=sync
Update the system:
sudo apt update -y && sudo apt upgrade -y
Set the correct hostname:
sudo hostnamectl set-hostname <new-hostname>
Correct the /etc/hosts file so that the new hostname resolves to 127.0.0.1
Tools

Install tools for configuring and debugging:
sudo apt install -y jq nano curl usbutils pciutils
Wireguard

Install wg:
sudo apt install -y wireguard
Paste wg config (make sure to remove IPv6 and adjust the MTU to 1340 and endpoint to 127.0.0.1:59401 if using wireguard-multipath):
sudo nano /etc/wireguard/wg0.conf
Enable wg connection on boot:
sudo systemctl enable --now wg-quick@wg0
wireguard-multipath

Install wireguard-multipath:
sudo wget "$(
  curl -s https://api.github.com/repos/blokadainfo/wireguard-multipath/releases/latest \
  | jq -r '.assets[] | select(.name | endswith("_linux_arm64")) | .browser_download_url'
)" -O /usr/local/bin/wgmp \
&& sudo chown root:root /usr/local/bin/wgmp \
&& sudo chmod +x /usr/local/bin/wgmp
Edit /etc/systemd/system/wgmp-client.service:
[Unit]
Description=Wireguard Multipath Client Service
After=network-online.target
Wants=network-online.target

[Service]
Type=simple
ExecStart=/usr/local/bin/wgmp client

WantedBy=multi-user.target

Reload and enable the service:
sudo systemctl daemon-reload && \
sudo systemctl enable --now wgmp-client.service
Audio

Install pipewire with pulse and alsa support:
sudo apt install -y pipewire pipewire-pulse pipewire-audio-client-libraries pipewire-media-session- wireplumber dbus-user-session alsa-utils pulseaudio-utils
Add user to audio group:
sudo usermod -aG audio $USER
Enable pipewire session on boot:
sudo systemctl unmask systemd-logind && \
sudo systemctl restart systemd-logind && \
sudo loginctl enable-linger $USER && \
sudo reboot
Set default output to 3.5mm jack:
pactl set-default-sink alsa_output.platform-es8316-sound.stereo-fallback
CRUCIAL STEP:
Using alsamixer (press F6, choose rockchip-es8316, press F5 to show all options) fix silence by unmuting "Left Headphone Mixer Left DAC" and "Right Headphone Mixer Right DAC".
Edit /etc/asound.conf:
pcm.!default {
    type pipewire
}

ctl.!default {
    type pipewire
}

Reboot:
sudo reboot
Test audio

Test alsa:
speaker-test -D default -c 2
Test alsa with audio file:
aplay -D default /usr/share/sounds/alsa/Front_Center.wav
Test pulseaudio with audio file:
paplay /usr/share/sounds/alsa/Front_Center.wav
Test pipewire with audio file:
pw-play /usr/share/sounds/alsa/Front_Center.wav
BiB Comms (headless Mumble client)

Install dependencies:
sudo apt install -y libopenal-dev libopus-dev libasound2-dev pkg-config ffmpeg
