Possibly html5 related, but I am quite ignorant about the whole thing.

Sound works fine in flash applications and pretty much everything else except, appparently, html5 players.

I have the following gstreamer packages installed:

gst-ffmpeg-0.10.13-x86_64-2ponce
gst-plugins-bad-0.10.23-x86_64-3ponce
gst-plugins-base-0.10.36-x86_64-2
gst-plugins-base-compat32-0.10.36-x86_64-2compat32
gst-plugins-good-0.10.31-x86_64-5
gst-plugins-good-compat32-0.10.31-x86_64-5compat32
gst-plugins-ugly-0.10.19-x86_64-2ponce
gst-python-0.10.22-x86_64-2ponce
gst1-libav-1.4.1-x86_64-1ponce
gst1-plugins-bad-1.4.1-x86_64-1ponce
gst1-plugins-base-1.4.1-x86_64-1ponce
gst1-plugins-ugly-1.4.1-x86_64-1ponce
gstreamer-0.10.36-x86_64-2
gstreamer-compat32-0.10.36-x86_64-2compat32
gstreamer1-1.4.1-x86_64-1ponce
gstreamermm-0.10.10.2-x86_64-1ponce
phonon-gstreamer-4.6.3-x86_64-1

I am listing these because on my search for a solution to this, which has been ongoing for several months now, gstreamer plugins have been mentioned in various threads.

I can't get it to work myself and the general internet searches haven't helped either, so I'm finally asking right here.

Any ideas how to fix this?
An example video:
http://vimeo.com/105441286

I have tried switching the HD option on and off, no change.
Videos play fine in mplayer. They do not play with sound in the browser.
Firefox is at version 35.0.1 but the problem has been orccuring since at least half a year, perhaps longer.

Fix:

Faulty asoundrc, renaming it to prevent it from loading fixed the issue.

I've ended up building my own Firefox version, linked against gstreamer 1.x. Your video works fine with that, including sound.

The gstreamer packages in Slackware are very old and end-of-life, according to the official website. Support is much better with newer libraries. Just installing gstreamer1 like you did won't work, Firefox has to be rebuilt to support it, too.

I've written a blogpost about that a while ago:
http://schmatzler.de/en/2014/05/26/y...lash-on-linux/

Packages for -current and SlackBuilds for Firefox and gstreamer are in my signature.

Edit: It also looks like gst1-plugins-good is missing in your setup.

do you have a .asoundrc file ?

since i wont come again today
gst is picky about outputs, so just mv .asoundrc .asoundrc_bak

Thanks for pointing out the missing plugin package, but, since you seem to be right about having to actually link FF against it, it didn't do anything.

Before I compile FF, though, let me ask you about the ready built packages you are linking to in your signature.

Is it intentional that there is a '1' after the name of each gstreamer package?

gst-libav1-1.4.4-x86_64-_banpack.txz
gst-plugins-base1-1.4.4-x86_64-_banpack.txz
gst-plugins-ugly1-1.4.4-x86_64-_banpack.txz
gst-plugins-bad1-1.4.4-x86_64-2_banpack.txz
gst-plugins-good1-1.4.4-x86_64-_banpack.txz
gstreamer1-1.4.4-x86_64-_banpack.txz

I'm asking because if I were to simply upgrade the packages I have with yours
then gstreamer1 would be replaced by yours while the other gst (as in,
gst-not-1) packages would not be updated since the naming convention is
'wrong'

Is this all the 'base' version of gstreamer, aka not gstreamer1? I don't want
to overwrite the real gstreamer1 with these packages, in case they're all the
non-1 version, but due to the 1-after-the-package-name would make sense in the
case of gstreamer/gstreamer1.

Sorry if I'm expressing myself in a confusing way, so here a tl;dr

Are these packages gstreamer or gstreamer1?

My packages are gstreamer 1.4, but they are named differently to the ones included in Slackware or on SBo, because they get installed into /opt. The Firefox SlackBuild also links against gstreamer in /opt. I did that so nothing else will interfere and I use the same gstreamer packages for Banshee, too.

The linked vimeo video "just worked" (pix + sound on firefox) on -current here. Nothing particularly non standard in the system. Here are my gst related packages - they were already installed:
gst-ffmpeg-0.10.13-x86_64-2_uqv
gst-plugins-base-0.10.36-x86_64-2
gst-plugins-good-0.10.31-x86_64-5
gst1-plugins-bad-1.4.1-x86_64-1_uqv
gst1-plugins-base-1.4.1-x86_64-1_uqv
gstreamer-0.10.36-x86_64-2
gstreamer1-1.4.1-x86_64-1_uqv
phonon-gstreamer-4.6.3-x86_64-1

I use pulseaudio - not sure if that's relevant ...

Hi Geist

Can you answer the question as to whether you have an .asoundrc file in your home directory. If you have can you post it here.

Also if possible can you post the results of Alex

@schmatzler and everyone suggesting to work with the asoundrc:

Well, after renaming mine so it wouldn't load anymore fixed it without needing anything recompiled, etc.

Odd, too. I have this really crappy headphone amplifier/DAC combo, the FiiO E10, and due to its cheap components going from silence to sounds playing the chip sometimes fails to play the first few milliseconds of whichever sound is playing.

The only fix I managed to conjure up two years ago was to try and force 96khz playback for everything. It fixed 90% of all regular problems and fiddling with mplayer configs and co things were peachy for pretty mcuh everything except some system notification sounds.

All seems fine now, however, so far.

I'll mark this thread as solved and if I get any sound troubles in general then I'll make a thread for that separately.

Thank you all for your time.

.asoundrc is not faulty, gstreamer is
and you'r welcome

In case it might be useful to someone still interested in this thread:

On my Debian 7/Wheezy system, one user got sound from a Vimeo URL, and another user got silence. This thread popped up while searching for a solution. The key difference was the use of the 'plug' feature in the .asoundrc file. This diff/patch took one user from silence to working sound with the original URL. My best guess is whatever Vimeo is using produces a specific sample rate, and putting the 'plug' feature in the .asoundrc file causes ALSA to convert the sample rate. (Fwiw: My system uses straight ALSA, no PulseAudio.)
