bug#68512: Qutebrowser 3, no sound from pipewire-only system

[chris]

Hello,

The latest qutebrowser v3 from this pipewire-only system has no sound. Related messages from the shell process pasted below include CJK characters which debbugs renders as "??", all CJK messages translate as "file or directory not found"
```

About a year ago, user @iyzsong enabled pipewire support at qutebrowser v2 for me and sound has been good here until today when qutebrowser v3 was installed.  iirc, a flag was enabled in qutebrowser or one of its dependencies.

yeah, debbugs doesn't support unicode on the web fully. But when 
checking your messages in emacs debbugs interface, I see the CJK 
characters just fine.

How is pipewire configured on your system? The thing is that 
qtwebengine@5 is linked with PulseAudio and ALSA libraries, but @6 
is linked only with alsa. You probably miss pipewire-alsa 
compatibility configuration. Do you use 
home-pipewire-service-type? It sets both pulse/alsa shims and it 
works for me this way.

This system does not use dbus and pipewire was configured about a year ago when there were few options for using pipewire out of the box in any sort of way.

Guix home is configured to write a pipewire and three wireplumber config files, as described at this link https://wiki.alpinelinux.org/wiki/PipeWire#Configuration

.config/pipewire/pipewire.conf
.config/wireplumber/wireplumber.conf
.config/wireplumber/main.lua.d/80-disable-dbus.lua
.config/wireplumber/bluetooth.lua.d/80-disable-logind.lua

With with those files in place, pipewire and wireplumber are started sequentially to get working sound. I use this in my .config/sway/config (possibly this is copy-pasted from unmatched-paren)
```
exec_always killall -wqr "(pipewire|wireplumber)" \
  || sleep 1 && ((pipewire &); sleep 2 && (wireplumber &))
```

Well, qtwebengine doesn't link with PipeWire anyway, you have to 
use either PulseAudio or ALSA. Here is an example 
~/.config/alsa/asoundrc on my system, created by 
home-pipewire-service-type. If you add such file to your setup - 
qutebrowser should be able to use alsa lib to output audio through 
pipewire.

Sergey,

Thanks for this help. Running `$(guix build pipewire)` returned the same path shown in your example, so I tried simply copy-pasting your example to ~/.config/alsa/asoundrc and restarting my system

Sound did not work, but messages in the qutebrowser process output were slightly different. foreign text translates as: "host dropped",
```
[1588:1588:0117/013614.549773:ERROR:alsa_util.cc(204)] PcmOpen: default,ホストが落ちています

[1588:1588:0117/013614.588043:ERROR:alsa_util.cc(204)] PcmOpen: plug:default,ホストが落ちています
```

These messages differ from the earlier messages that basically said "file not found".

Thanks for helping me. I will sleep now and maybe try more things tomorrow,

Chris

The english variant of the same message is probably "Host is down"

Sergey, your configuration file is working and audio is heard from qutebrowser on this system.

Internet searches surfaced commands like these,
 `pw-cli`
 `strace -e connect pw-dump >/dev/null`

Error messages were seen relating to socket files not found,
 `$XDG_RUNTIME_DIR/pipewire-0`
 `$XDG_RUNTIME_DIR/pipewire-0-manager`

Various things attempted, but the socket files missing every time sway started

Finally, tried removing the pipewire-starting parts of the sway config
```
# exec_always killall -wqr "(pipewire|wireplumber)" \
#   || sleep 1 && ((pipewire &); sleep 2 && (wireplumber &))
```

Then separately started pipewire and wireplumber "manually" from the shell. The socket files were created and when qutebrowser sound could be heard.

Thank you Sergey,

Chris

I'm glad you sorted it out. Check what are the environment 
variables for your sway process (cat /proc/<pid>/environ | tr -s 
'\0' '\n').
Maybe XDG_RUNTIME_DIR is missing there? Enabling debug logging for 
pipewire might help as well: 
https://docs.pipewire.org/page_daemon.html

Sergey,

Yesterday after reporting back here, I found that I was able to change the commands used by sway from this
```
exec_always killall -wqr "(pipewire|wireplumber)" \
  || sleep 1 && ((pipewire &); sleep 2 && (wireplumber &))
```

To this
```
exec sleep 2 && pipewire
exec sleep 4 && wireplumber
```

sound is working each time the machine is started or restarted.

In order to script-generate the asoundrc file, I wish to use pipewire's store directory path inside a scheme function. WOuld you teach me how to do this? eg, `$(guix build pipewire) # /gnu/store/8572wxb5138hanhvn1lbfdm1kicxsd2k-pipewire-1.0.0`

No success trying various things from this thread https://www.mail-archive.com/help-guix@gnu.org/msg11871.html

'have also tried the following
```
(use-modules (gnu packages linux)
             (gnu packages build-tools)
             (gnu packages package-management))

(guix build pipewire)
```

running the file fails with this message:
```
Wrong type to apply: #<package guix@1.4.0-15.e0885fc gnu/packages/package-management.scm:179 7fd6dfe0ebb0>
```

Thanks in advance for any recommendations or advice. Thank you for conversing with me and helping me thus far,

Chris

Ugh, why don't you use home-pipewire-service-type?

Packages are file-like, i.e. replaced with their location when 
used in g-exp.
Here is an example how to define the configuration, I've adapted 
it from gnu/home/services/home.scm

0.3.77 is the previous version, from a month ago. Is your checkout 
fresh? Did you `guix pull`?

`home-pipewire-service-type` has no option to skip dbus and thus far this system does not use dbus, ibus, elogind and systemd etc.

Interesting. Thanks for teaching me this.

The above does work :) thank you. I'm interested to explore writing a function that wraps g-exp behaviour to return a package as store path string and might do that outside of this ticket.

Thank you for your kind help and correspondence,

Maybe you should check your GUILE_LOAD_PATH and
GUILE_LOAD_COMPILED_PATH.  That's where guile finds the guix modules.
They might include folders from an old guix.

The only dependency on `dbus` is that pipewire shepherd service 
has it in the requirement field.
You can add a no-op shepherd service which would have (provision 
'(dbus)) to satisfy the dependency.

I'm not sure how to investigate or verify that but here is the result of echo

$ echo $GUILE_LOAD_PATH 
/home/bumble/.guix-home/profile/share/guile/site/3.0:/run/current-system/profile/share/guile/site/3.0
$ echo $GUILE_LOAD_COMPILED_PATH 
/home/bumble/.guix-home/profile/lib/guile/3.0/site-ccache:/home/bumble/.guix-home/profile/share/guile/site/3.0:/run/current-system/profile/lib/guile/3.0/site-ccache:/run/current-system/profile/share/guile/site/3.0

`.guix-home/profile/share/guile/site/3.0` only has a few symlinks ice-9/  ncurses  shepherd  shepherd.scm

`/run/current-system/profile/share/guile/site/3.0` has many more symlinks

I don't know how to do this. If you share links to documentation or examples I will read those. It would be nice to use the home-pipewire-service rather than manage these files myself.

Thank you and thank you for any further suggestions or advice you may give,
