systemd containers

Assumptions

This how-to uses mybox as container name, mkosi in order to create containers (it works for multiple distributions and has more features compared to dnf --installroot), and crudini for configurations file (you can use your preferred text editor instead).

How to create a container with mkosi

# mkosi --cache /var/cache/mkosi -d fedora -t directory -o /var/lib/machines/mybox

Affected devices

• Bowers & Wilkins PX7 19b5:0025 B & W Group
• Dali IO-6 0a12:0001 Cambridge Silicon Radio

Fix

The best way to fix that is to use PipeWire, since it allows to set rules for a specific device only, instead of having to change the sampling rate of the whole audio system.

PipeWire
