This may be a crazy idea--but why don't we just make the default output device "all devices"--copy the audio streams to every device until the user selects a specific device as the default. This would neatly solve the issue in this thread as well as other peoples' confusion of "why do I have no sound" when the sound is being directed to a card without any speakers attached. There should be a way to override this system-wide default as well. Alternatively, perhaps hal-based quirks can specify the system-specific default sound output device. e.g. for laptops or desktop models the built-in soundcard would be a sane default. If there is no hal quirk for the current system, you could fall back to "all output devices" or the heuristics you describe above. Basically: 1. system factory default: output to all sound cards simultaneously 2. system custom default: either hal-quirk based, heuristic-based, or set by sysadmin. 3. per user setting: as we have now, per user default output device setting. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
