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.
Erik
hi
for firefox from v52 onwards
pulseaudio should work and it is the preferred linux sound system
alsa & jack don't work and need a locally built from source version of
firefox
I use jack so I need the alsa system until the native jack is fixed
