Trying firefox on a fresh install of debian 9.0.0, it plays youtube
video fine - sans audio. To figure out whether the silence is due to me
having to do something more than hook up the hdmi cable and check that
the monitor's speakers are unmuted and set to 50%¹, I thought I'd try
www.abc.net.au/news and click on the link to the 24 hr news tv channel.
But that evinces an "Error loading player: No playable sources found."
OK, I did an apt-get install mplayer, with the same result. Then I
added:
deb http://mirror.optus.net/deb-multimedia/ stable main
to /etc/apt/sources.list, and after that an apt-get update:
# apt-get install deb-multimedia-keyring
gave "E: Unable to locate package deb-multimedia-keyring"
In contrast, this older debian wheezy host plays both sites fine.
It would be especially nice to get the audio working, as this new Udoo X86
was bought for its claimed ability to stream to three 4K screens
simultaneously.
¹ I also tried an hdmi to vga adaptor, with stereo audio cable plugged into
the monitor's audio jack (and the monitor menu-switched to vga mode),
but that also gave only silent movies.

hi
from firefox 52 onwards only pulseaudio is in the compiled release
alsa can be activated by compiling a local version of firefox with
ac_add_options --disable-pulseaudio
ac_add_options --enable-alsa
in the firefox-mozconfig file
the alsa driver will be dropped from the source at some stage

Hi Steve,
That's interesting, but I'm still catching up. Are you saying that
pulseaudio does not work, and thus is the most likely cause of no audio
on the hdmi with firefox 52.2.0 on debian 9.0.0?
And if pulseaudio is the problem, then why is it that the alsa driver
will be dropped?
I'd thought that I'd just missed some install/config step. It beggars
belief that debian 9.0.0 would be released with a firefox from the silent
movies era - and still not be fixed. =8-O
Clicking on "Sound & Video" -> "PulseAudio Volume Control"
shows
"Firefox AudioStream" to be at 46% (-20.25 db). Holy smokes! that's 3/5
of BA. I cranked it up to 100%, which is still only 0 dB, but still
no sound. The VU-meter bar under that control is flapping about
vigorously, so there's audio coming from firefox - it's just stuck in
there.
The "Output Devices" tab provides two options at "Port":
Speakers
Headphones (unplugged)
That's hopefully just a distraction, because hdmi is only hdmi when it
has audio.
It's late. Mañana.

Thanks, Steve. A second evening of perseverance revealed the deeply
hidden secret. The "Sound & Video" -> "PulseAudio Volume
Control" menu
item has only 3 widely spaced tabs, underutilising the available space,
and the "Output Ports" tab offered no management/configuration
possibilities.
But there are two tiny dark triangles in the corners, and clicking on
the RH one leads to an extra hidden tab, "Input Devices", and clicking
again reveals "Configuration". There, in a "Profile" selection box,
it
is possible to select "Digital Stereo (HDMI) Output". Once selected, it
even seems to be the power-on default. (Much to my surprise, given the
user-hostile perversity of the devious GUI design.)
Granted, the purpose of a GUI is to put access to necessary functions
at the end of deep maze rat runs - but invisible secret tabs with double
blind access?! I do believe that some of these devs are being paid by
Microsoft to paralyse linux. (If not, we know that they were born
arse-backwards, and have never turned around.)
