Comment 1

[Sylvestre Ledru [:Sylvestre]]

about:support makes me crash too.
Paul, rings a bell?

Comment 2

[Paul Adenot (:padenot)]

Dan, looks like cubeb has not been initialized, or that the initialization has fail.

Sylvestre, does flipping `cubeb.sandbox.enabled` seem to "fix" the issue for you? It's not really a fix, but maybe allows sidestepping the problem.

Comment 3

[Sylvestre Ledru [:Sylvestre]]

Yeah, fixes my issue and I can even play the video (it wasn't starting before)

Comment 4

[Sylvestre Ledru [:Sylvestre]]

This is causing firefox to be unusable on Linux (at least with configuration similar to mine)

Comment 5

[Sylvestre Ledru [:Sylvestre]]

Attachment: about:support

on the request of Mr Adenot.

Does this mean you have pulse installed but the server isn't configured?  I'd like to be able to reproduce locally to test out the code.

Do you still have problem in cubeb_enumerate_devices() after Bug 1441588 landed?

Comment 8

[u480271]

OK. I reproduced the about:support crash. This is different to Bug 1441588.
