1445656 - JACK sound not working in Firefox 58

Status: RESOLVED DUPLICATE of bug 783733

(Firefox :: Untriaged, defect)

Description

[Turbo]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0
Build ID: 20180314085616

Steps to reproduce:

Arch Linux FF 59 stock version build with --enable-jack. Launch it and attempt to play some audio file.


Actual results:

Nothing happens, no sound. It even don't work with a loopback sound card (ALSA >> JACK).

FF launched trough a terminal/consol gives:

Sandbox: seccomp sandbox violation: pid 3604, tid 3716, syscall 49, args 53 140516787704640 110 0 13 0.

Expected results:

There should be sound like in previous version (FF 58).

Hi Turbo, based on bug 783733 comment 98 it seems that you found a workaround for Firefox 59 release and also the issue is no longer reproducible on Firefox 60. 
Considering the above and the fact that the issue is tracked in bug #783733, I will close this issue as a duplicate of it.
