This happens when you start the = audio or video by clicking on the play button and also when audio or videos= are played automatically (in a playlist, or ad videos, for example). This issue has been reported before upstream, but epiphany people say the s= ource of the problem is in pulsaudio defaults on distros (https://gitlab.gn= ome.org/GNOME/epiphany/issues/73): Thanks for reporting this issue. You'll need to ask Debian to disable PulseAudio's flat volumes feature, as is done by all other major distributions (Ubuntu, Arch, Fedora, openSUSE, probably more), since we're not going to make any changes here. I found that there is a related pulsaudio bug reported on Guix (https://iss= ues.guix.gnu.org/issue/38172). Unfortunately, this issue is still open. Epiphany people say you, as a user, can work around the issue by setting "f= lat-volumes =3D no in your /etc/pulse/daemon.conf." What's the correct way = to this on the Guix System? I'm using this software: epiphany 3.30.4 WebKitGTK+ 2.26.1 GNOME 3.30.2 $ guix describe Generation 16=09Jan 03 2020 14:36:37=09(current) guix 7158fe4 repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: 7158fe4ded47a599ceb8d556132ba83fcc686962
