* and the headphones get unplugged, then the headphone device must be set
|
|
* to unavailable and the speaker device must be set to unknown. So far so
|
|
* good. But there's an ugly detail: we must first set the availability of
|
|
* the speakers and then the headphones. We shouldn't need to care about
|
|
* the order, but we have to, because module-switch-on-port-available gets
|
|
* separate events for the two devices, and the intermediate state between
|
|
* the two events is such that the second event doesn't trigger the desired
|
|
* port switch, if the event order is "wrong".
|
|
*
|
|
* These are the transitions when the event order is "right":
|
|
*
|
|
* speakers: 1) unavailable -> 2) unknown -> 3) unknown
|
|
* headphones: 1) available -> 2) available -> 3) unavailable
|
|
*
|
|
* In the 2 -> 3 transition, headphones become unavailable, and
|
|
* module-switch-on-port-available sees that speakers can be used, so the
|
|
* port gets changed as it should.
|
|
*
|
|
* These are the transitions when the event order is "wrong":
|
|
*
|
|
* speakers: 1) unavailable -> 2) unavailable -> 3) unknown
|
|
* headphones: 1) available -> 2) unavailable -> 3) unavailable
|
|
*
|
|
* In the 1 -> 2 transition, headphones become unavailable, and there are
|
|
* no available ports to use, so no port change happens. In the 2 -> 3
|
|
* transition, speaker availability becomes unknown, but that's not
|
|
* a strong enough signal for module-switch-on-port-available, so it still
|
|
* doesn't do the port switch.
|
|
*
|
|
* We should somehow merge the two events so that
|
|
* module-switch-on-port-available would handle both transitions in one go.
|
|
* If module-switch-on-port-available used a defer event to delay
|
|
* the port availability processing, that would probably do the trick. */
