[PATCH] core: ignore devices that are not linked when choosing the default sink or source

[tanuk@xxxxxx (Tanu Kaskinen)]

Sources should probably be added to pa_core.sources in pa_source_put(),
but currently they're added in pa_source_new(). A lot of stuff can
happen between the pa_source_new() and pa_source_put() calls, and
it has happened that the default source was updated during this time.
Therefore, pa_core_update_default_source() needs to take it into account
that not every source is necessarily linked.
