Is this on Guix System or another distro?

Could it be #40832 (alsa-lib cannot find its plugins)?
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=40832

That bug breaks audio of Guix applications on foreign distros in many
cases.

Closing due to lack of info. Please feel free to re-open if the bug
still occurs :)

bug#45280: qutebrowser has no audio

Sorry I don't think I saw the previous reply. Absolutely still a
problem. I am on Guix System. It is not at all a system-wide issue. Most
things have sound working fine.

Here's some output when I launch qutebrowser from a terminal. It seems
like it may be using ALSA instead of pulse for some reason.
```

bug#45280: Qutebrowser doesn't display embedded mp4.

[jcguu95]

Hello,

I'm on guix system with the latest `qutebrowser' from the official
channel. While reading this [site] I realize that embedded mp4 files do
not play well. Turning on qb again from the terminal allowed me to see
the complaints. I believe this could be related issues to OP, so decided
to post it here.

bug#45280: qutebrowser has no audio

[bdju via Bug reports for GNU Guix]

I have finally gotten sound working. I needed to enable an alsa service
(which also required the sound and possibly audio use-service-modules)
aplay and speaker-test were failing, which seemed to possibly be due to
a lack of /etc/asound.conf, and I found in the manual that the alsa
service creates this file. After enabling that service, I just had to
restart qutebrowser.
As an aside, I think if our qutebrowser package were built with the
optional pulseaudio support enabled, I would never have hit this issue.
Although you could argue that having broken alsa was probably not good
anyway.

I will finally close this issue.
