Thanks for working on this! Sorry for slow review, I hope I'll be much

And the preferred_sink is only set when user is calling the

If the target of move_to() is default_sink, preferred_sink will be
cleared and the entry->device will be cleared too from database.
Can you split this so that the first patch only changes save_sink to
preferred_sink, without any changes in behaviour? That is, put the
"don't move the stream in the module-stream-restore" and "if the target
of move_to() is default_sink" logic into separate patches.
Also replace tabs with spaces.
OK, got it, will addressed all comments.

What's the goal here? The client tries to change an entry in the
stream-restore database, why should that change be ignored if the
current default sink happens to be the same as the new device? Maybe
you intended to set entry->device to NULL in this case. But I don't
think that's necessary either - if the client wants to unset the
device, it can just give NULL as the device name. I don't think you
need to change anything here.
By the way, m->core->default_sink can be NULL, so that would have to be
checked if this code was kept.
Actually I didn't change this part first, but I remember the stream bond
did not work as expected, after changed as above, it worked as expected.
Supposing sink0 is hdmi, and is playing a music over sink0, sink1 is
speaker, after I unplugged the hdmi cable, the music is switched to
speaker, but music->preferred_sink is still sink0-hdmi, after I plug
the hdmi cable again, the music should be switched back to sink0-hdmi.
I remember after I unplugged the cable, a user-space app call
extension_cb to set the music->preferred_sink to be sink1-speaker
(default_sink), then the music can't be switched back to hdmi anymore.
I will test it again, if it is really not needed, I will drop these code.
I would guess that it's gnome-control-center that sets the device to
speakers when you select speakers as the output. gnome-control-center
updates the routing in all stream-restore entries. Once these patches
are merged (and once a new release is made), gnome-control-center can
be fixed to not mess with the stream-restore database any more. I
believe the current gnome-control-center behaviour is a workaround for
the fact that PulseAudio hasn't so far automatically moved streams when
the default sink changes.
Yes, it is gnome-control-center. OK, will drop this part.
