I guess you are more familiar with the use cases, but wouldn't it be common to attach a monitor without wanting to use the monitor's audio output? If that's the case, I think auto-switching isn't really a good idea. If you are going to do the auto-switching anyway, I think the default sink should be changed too. Behaving differently with existing and not-yet-existing streams doesn't make sense to me. > * switching only if the HDMI outputs are on the same card as the > analog output.

For what it's worth (I'm not a usability expert), to me the last option sounds the best policy, with default sink updating. -- Tanu
