Hi all
As Ken noted, Firefox 58 seems to have some sound issues. I could not
confirm this on all my boxes, but found out that one box has the issue,
while the other has not. But are using alsa and the same, self-compiled
firefox 58b16.
A solution on the faulty machine is to start firefox, go to
about:config, and then set the property
security.sandbox.content.level
to 0, instead of 3.
Why this is only necessary on one machine and not the other, is beyond
my knowledge.
Will let you know if I find anything more about this. Both machines run
a 4.14.13 kernel and alsa 1.1.5.
The warnings in firefox stderr when it doesn't work is:
Sandbox: seccomp sandbox violation: pid 3941, tid 4030, syscall 16, args
48 2147767296 139909894784796 0 0 0.
