Synchronise mute and volume between lightdm and respective user sessions

[Conor Curran]

Currently when at the login screen if the user mutes the volume and then logs in the mute state is not 'carried over' into that users session.

why not sychronise audio state between login screen and user session.

I'm kinda thinking that it would be easier to do this in the indicator-sound. Only because I can tell when I'm in the greeter and also have communication with the pulse daemon setup. Therefore I will be able to write to the accounts service quite easily from the service on volume state change.

Just remember that you will have to get the greeter to tell the indicator which user is selected so you know which user in AccountsService to modify.

[Conor Curran (cjcurran)]

yep thanks Robert, Will start patching in the next few days.

On my backlog...

Confirmed on Ubuntu 12.04 with unity-greeter 0.2.8-0ubuntu1.
It's LTS, guys! Do not be a Windows Vista!!

I'm unassigning me from this bug, because I don't see this happening in the near future.

This should be doable just within indicator-sound these days. The greeter shares which user is selected over DBus. And indicator-sound can register a custom field with AccountsService by itself.

See https://code.launchpad.net/~mterry/telephony-service/greeter-contacts/+merge/199910 for an example of adding a new field and listening for greeter user changes (though granted, that's qt code instead of glib.

This has become more important with the phablet images, since once we split the greeter, the user will definitely have the expectation that volume changes in greeter will carry over.

Indicator-sound itself supports this now. It just needs accountsservice-ubuntu-schemas to be installed. Which it is on touch. And could be on desktop if we wanted to modify the ubuntu-desktop metapackage.
