Eventually we want to tag each stream with a property that would implement these categories as you've done, but sadly as pulse works with a lot of other apps via protocols that do not support metadata (e.g. OSS/alsa etc) many apps will not set these properties. There fore we will have to have some kind of heuristic database to try and tag things properly (this should be easy enough with a module and a simple database, even if it is a little hick :)). > - Is there a way to check if a stream is actually producing sound not > just active... flash player in ff does not seem to play nice?? This particular issue is a bug with flash as far as I can tell. I'm not sure if the API tells you if a stream is paused or muted or not, but like I say I suspect it wouldn't help in the FF case anyway. Perhaps someone more knowledgeable will be able to give better info ;) Col -- Colin Guthrie gmane(at)colin.guthr.ie http://colin.guthr.ie/ Day Job: Tribalogic Limited [http://www.tribalogic.net/] Open Source: Mandriva Linux Contributor [http://www.mandriva.com/] PulseAudio Hacker [http://www.pulseaudio.org/] Trac Hacker [http://trac.edgewall.org/]
