www-client/firefox built with the jack use flag fails to add jack capture ports in web pages which want a capture device. The issue is that the jack backend in libcubeb refuses to create a stream if there is already a device defined. When adding an input stream, the output device is already defined, triggering the error return. I've opened an issue on cubeb's tracker, but it is likely to take a while to get it resolved and merged into firefox itself. In the meantime, a patch for building firefox is pretty simple. diff media/libcubeb/src/cubeb_jack.cpp.orig media/libcubeb/src/cubeb_jack.cpp 746c746 < if (input_device || output_device) --- > if ((input_stream_params && input_device) || (output_stream_params && output_device))

Oh, of course. https://github.com/kinetiknz/cubeb/issues/550
Alright, it's been fixed in the upstream library. It'll take a while to get into the current firefox source, and won't ever reach the released versions of firefox. The patch from upstream can easily be applied to existing ebuilds, and has a bit of sanity checking. If we can apply it to the current ebuilds, it would make the jack use flag more useful for firefox. The relevant commit is https://github.com/kinetiknz/cubeb/pull/552/commits/5dc6a4d79c29d7cf2ecd65efb4401d860140b1cb
Closing as obsolete. Vanilla firefox-74 includes these changes.
