App plays notification sound when opening a task while alt-tabbed away

Reported by Rafa in Slack:

> Code sometimes meeps for no reason.
>
> I believe the flow is: open a task that I haven't opened in the current run, immediately alt tab while it's loading the state, once state is loaded it meeps.
>
> It's not really waiting for some input/finished, it's only finished loading the task, so... probs bug?
