If you select the fallback recording stream before you start recording, that's what VLC will get as the source. Also, if you select a source for VLC, it will "stick" thanks to module-*-restore, so after setting it once, you'll get that until you change it again. Or other things happen, like external headsets connected and stuff. There was a lengthy post about routing (and its future) from Colin Guthrie, but I can't find it now...

Show me one modern media player that has output devices choice list. Or video conferencing, where it would make even more sense (hint: neither Skype nor Empathy allow you to select sinks/sources). Volume control in e.g. banshee is just a proxy to PA. That's just how it was designed, and on purpose. I can imagine a common (just as printing is now <but wasn't not so long ago> - you generally always should get a printing dialog you know well) dialog for advanced applications to choose sinks and sources for a particular app / role on demand. But I'm not sure that's necessary and I haven't seen anyone step up and write it. Another thing I could imagine is a media role (are those even implemented for sources?) of "desktop-recorder" or similar, that will choose the monitor of the active sink for you. That's as far as I'd go, TBH, to handling this case. Cheers, -- Micha? (Saviq) Sawicz <michal at sawicz.net> -------------- next part -------------- A non-text attachment was scrubbed...
