Here is the qutebrowser 3 process shell output. Would anyone recommend a solution?

Have you installed qt-wayland?  Are you setting QT_QPA_PLATFORM
anywhere?

Hey Josselin,

I've tried installing qtwayland through guix home by specifying "qtwayland" in my home config file. QT_QPA_PLATFORM is specified in my home config this way
```
(simple-service 'env-vars home-environment-variables-service-type
   '(("EDITOR" . "emacs")
     ("OPENER" . "sh.opener.sh")
     ("BROWSER" . "qutebrowser")
     ("GTK_IM_MODULE" . "fcitx")
     ("QT_IM_MODULE" . "fcitx")
     ("XMODIFIERS" . "@im=fcitx")
     ("QT_QPA_PLATFORM" . "wayland")
     ("QT_SCALE_FACTOR" . "1")
     ("XDG_SESSION_TYPE" . "wayland")
     ("XDG_SESSION_DESKTOP" . "sway")
     ("XDG_CURRENT_DESKTOP" . "sway")
     ("DESKTOP_SESSION" . "sway")
     ("LIBSEAT_BACKEND" . "seatd")))
```

QT_QPA_PLATFORM prints at the shell this way
```
$ echo $QT_QPA_PLATFORM
wayland
```

I tried changing "qtwayland" to "qtwayland <at> 6.5" in my home config and reconfiguring home. I've also tried installing qtwayland without guix home using "guix install qtwayland" but those did not resolve the issue.

I can try any suggestion and if it doesn't work, revert back using guix home switch-generation

Here you go:
```sh
qtw=$(guix build qtwayland <at> 6)/lib/qt6/plugins
QT_PLUGIN_PATH=$qtw QT_QPA_PLATFORM_PLUGIN_PATH=$qtw/platforms qutebrowser -s qt.force_platform wayland
```

Maybe a qutebrowser-wayland package variant should be defined to do the
required wrapping. Otherwise you can just install qtwayland <at> 6 to your
profile and use ~/.guix-home/profile/lib/qt6/plugins in paths.

Neither approach succeeded for me. What am I doing wrong...
```sh
$ ls $qtw

wayland-decoration-client/  wayland-graphics-integration-server/

I tried this command again just now and succeeded this time. I must have done something wrong the first time.

I think it needed the extra slash after at the end of $qtw... the shell output looks problematic, but otherwise the browser has started. Thank you

Qutebrowser 3 does not have sound and this appears in the process output. "そのようなファイルやディレクトリはありません" means "the file or directory is not found".

Sound works for me both in X11 and Wayland environments. I use 
pipewire though.

Hi,

Would this work with non-wayland users too?  (So that it would make
sense to add it to the main package?)

Thanks,
Clément

Yeah, it would work, but forcing the platform through parameters 
is not necessary. I added it just to be sure that wayland is being 
used instead of xcb. On the other hand I think adding qtwayland 
dependency to every qt-based gui program doesn't make sense. Maybe 
a qtwayland-home-service makes more sense which would install the 
dependency and set required environment variables. This way it 
would work for every Qt GUI program on wayland.

As simple as:

--8<---------------cut here---------------start------------->8---
(simple-service 'qtwayland-vars-service
 home-environment-variables-service-type
  `(("QT_PLUGIN_PATH" . ,(file-append qtwayland

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.

The snippet should be attributed to Sergey, my apology for incorrectly editing the reply

I'm not sure what the correct protocol or etiquette is but I think this issue could be closed by sending an email to 68483-done <at> debbugs.gnu.org

Maybe the 'done' email should be sent from Sergey who provided the solution?

I would like to close this issue and open new separate issues for sound and the PermissionError shown in the process output around 'qtwebengine_devtools_resources.pak'
