This works here. After adding the above to my home config, qutebrowser starts as `qutebrowser` without the extra params.

As for the sound issue, this system uses pipewire only, without dbus. mpv, musikcube and the previous version of qutebrowser have/had sound. When I first setup guix about a year ago, qutebrowser 2 did not produce sound and, to resolve the issue, Iyzsong, in the matrix or irc channel, said they would enable native support for pipewire through a flag at qutebrowser (or maybe one of the dependencies... I don't remember) and the next day after pull and reconfigure the sound began working and there were no sound problems until updating to qutebrowser 3 today.
