Description Max Perl 2016-07-03 17:31:22 CEST
Description of problem:
The audio is disturbed in some websites. Youtube works very well! But e.g. videos on facebook sound terribly! 
Please note that the related videos don't work in Firefox, too. So it seems to be a codec problem.

Version-Release number of selected component (if applicable):
chromium-browser-stable-51.0.2704.103-1.mga6.src.rpm

How reproducible:
Test it on the Helene Fischer facebook site (not my favourite music, just for testing ;-) )

Steps to Reproduce:
1. Go to https://www.facebook.com/helenefischer.official/
2. Try to watch a video there...

The short movie clips on that page play fine both with chromium 53.0.2763.0 on cauldron and with 51.0.2704.103 on mga5. The difference I see compared to youtube clips is that youtube uses opus for audio while facebook uses AAC. You can check yourself by browsing to chrome://media-internals in a different tab. Maybe the problem you see has something to do with the audio output setup? I don't use pulseaudio for example, so in my tests chromium outputs audio directly to ALSA.

Dear Christiaan,
Thanks for your answer. I am not sure wheter pulse is running. My desktop environment is GNOME 3.20.3. But the command "pulseaudio --check" returns nothing (if it is running it should return "0" I think, or?). Here the copied terminal content:

[maximilian@localhost ~]$ pulseaudio --check
[maximilian@localhost ~]$

When I try pulseaudio -D, I get the following error:

E: [pulseaudio] main.c: Start des Daemons fehlgeschlagen.

Here the output of the chrome://media-internals (perhaps it is helpful for finding a solution):

PS: Indeed, the videos works also on my machine under Mageia 5 without problems. The problem occurs only in Mageia 6...
Comment 4 Max Perl 2016-07-04 22:44:35 CEST
Hello again,
it is very wired. I have installed googles chrome (Version 51.0.2704.106 (64-bit), and there the audio of the video is not crackling. I am really puzzled.

Can anyone confirm the audio problems?
Comment 5 Max Perl 2016-07-06 12:47:11 CEST
Dear all,
After reinstalling, everything works fine. Perhaps I forgot to implement the taint repos in my previous installation. So I think the bug report is fixed. Sorry if the report was redundant?!
