About the sound, I believe you will need to expose the pulseaudio and/or pipewire sockets. You can reference bubblewrap configuration since it also works by sharing/exposing files. https://wiki.archlinux.org/title/Bubblewrap/Examples#Chromium
Thank you, that helped me progress. I noticed there were errors about not being able to connect to DBUS, now the following got rid of those: guix shell -C -N -P --no-cwd \ --share=/dev/ \ --preserve='^DISPLAY$' --preserve='^XAUTHORITY$' --expose="$XAUTHORITY" \ --preserve='^DBUS_.*' --expose=/var/run/dbus/system_bus_socket \ --expose="$XDG_RUNTIME_DIR/pulse" \ ungoogled-chromium -- chromium --app="https://meet.jit.si"; With this, I can use the microphone (there is no default microphone available, but my internal microphone can be selected and works), but I still have no sound. ALSA throws the error "The field ipc_gid must be a valid group (create group audio)", and indeed /etc/group in the container doesn't contain an audio group (only users and overflow). But `--expose=/etc/group` prevents the creation of the container with the error "guix shell: error: rename-file: Device or resource busy". So the next question is: how does one uses groups in the container?
