There are no errors about missing codecs or anything like that. The media plays, but there is no audio coming out from the speakers (which are on). Audio and speakers worked fine in the distro I was using before installing GNU with Guix.

I do *not* experience this issue on GNOME.

I presume you are using %desktop-services in your configuration.

When you run:

guix environment --ad-hoc alsa-utils
alsamixer

Is the volume turned off or is the sound card muted?  You can mute and
unmute with the M key and select your sound card with the F6 key.

There also is a program `speaker-test` in alsa-utils for basic testing.
