With Tuesday's release of iOS 11.4 and tvOS 11.4, Apple has finally rolled out much anticipated support for AirPlay 2 and named a few dozen third party speaker systems that are expected support the new multi-room audio technology in the near future.

Among the list of speakers supporting AirPlay 2 are by Bang & Olufsen, Denon, Libratone, Marantz, Naim, and Sonos. While many of them are already on the market, such as those by Sonos, all of them are listed only as "announced" pending updates.

Only the Apple HomePod supports AirPlay 2 as of Tuesday. The long-delayed streaming format's main upgrade is multi-room audio support, letting people pump sound across multiple speakers, or shift it from one room to another.

Third-party products set to gain support include:

There are no dates associated with the listed products, so it isn't clear precisely when support from the vendors will arrive.

Missing are other brands Apple has teased, namely Bluesound, Bose, Bowers & Wilkins, Marshall, and Pioneer.
