No audio during video playback

STR:

1. Try to play a video with audio, for example:

https://media.libreplanet.org/mgoblin_media/media_entries/2070/FSFKeynotewithSlidesHighRes.ogg

EXPECTED: The video should play with audio.

ACTUAL: There is no audio and a notification shows up saying: "To play audio, you may need to install the required PulseAudio software" + button "Learn how". But pulseaudio is already installed and works with other apps:

[~]: rpm -q pulseaudio pulseaudio-9.0-8.1.x86_64

Security level is set to "Safest"

I tested the video using TorBrowser 7.5.3 with the safest security setting and the audio works fine.

1. Close TorBrowser and delete the TorBrowser-Data folder.
2. Open TorBrowser and visit the link again and click on the video space and click Temporarily allow.
3. refresh the page if the video is not visible.

Hm, hard to tell what is going wrong. I have no issues with sound on my Debian box but it seems there are quite a bunch of Firefox users that do, see e.g.:

https://forums.linuxmint.com/viewtopic.php?t=262962 https://www.reddit.com/r/firefox/comments/7w171n/to_play_audio_you_may_need_to_install_the/

Does any of the workarounds mentioned there help at least?

I didn't read through all the info on the links (sorry, too long and I can't spot the actual workaround). But I forgot to mention something important: I am running TBB installed through torbrowser-launcher in openSUSE which comes with an AppArmor profile. Now I tried downloading the official Tor browser and in it I can play video with audio. So I suppose that should be reported to openSUSE?

FWIW on each start of Tor browser (the openSUSE's one, not the official) in journalctl I see:

Apr 30 19:53:27 pc kernel: firefox[9287]: segfault at 0 ip 00007fa91b876cff sp 00007ffd5cd045c8 error 6 in libxul.so[7fa9196d1000+4413000] Apr 30 19:53:28 pc dbus[1411]: [system] Failed to activate service 'org.bluez': timed out Apr 30 19:53:31 pc systemd-coredump[9288]: Process 9287 (firefox) of user 1000 dumped core.

Could AppArmor be causing all this?

Could be, yes. Let us know when you find out what is actually causing this and how to work around it. Meanwhile I'd say this is not a Tor Browser bug.

It seems related to the apparmor profile indeed. When I stop it I get no segfaults and audio works as expected. Reported to openSUSE, hopefully they will fix it.

Sorry for bothering.
