SOSUS (according to the public maps) is very focused on the Pacific and Atlantic oceans and a lot around Russian territorial waters. The network is probably a bit denser than represented on the map but there's not much need for it in the Indian Ocean.
(according to the public maps) is a good disclaimer to add. If you believe those maps, they are basically disregarding the Persian Gulf for example, to a degree that I find wildly inconsistent with the volume and intensity of US diplomatic, political and military intervention in the area. I strongly suspect they've got the whole area mic'd, but under a new program that's "deployment-specific" and more secret. But if they were to offer their observations to the search effort, they would be exposing the existence and possibly the locations of any hydrophones.

I'm not so sure SOSUS is largely an anti-submarine tool and the main countries the US would worry about tracking with subs are Russia and China.
