Comment 134 for bug 1711337

Hi James, I have tested your
firefox_59.0.2+build1-0ubuntu0.14.04.4_armhf.deb on a
Debian GNU/Linux 9.4 (stretch) and Rockmyy's
Linux tinkerboard 4.17.0-rc3-RockMyy-Seventeen

Any push to the Sound slider quiets sound permanently but the mute
button works ok when
looking a video from youtube.com, areena.yle.fi

Chromium (Version 63.0.3239.84 (Developer Build) built on Debian 9.3,
running on Debian 9.4 (32-bit)) has no problems with the slider.

I know that 4.17.0-rc3 is not supported yet but a problem may lay on the path.

Regards Lars
