Pioneer and Onkyo have released a series of firmware updates to enable the Chromecast Audio streaming capabilities in their products. You can then start streaming from any compatible app on iOS, Android, Mac, Windows and Linux PCs. It is connected via Wi-Fi connectivity and there are sampling rates of up to 48 kHz supported for lossless sources.
Chromecast built-in allows the use of other apps while streaming music. Users can answer calls, send emails, or play games without interrupting audio playback. The platform also enables streaming of single or multiple audio sources to other Chromecast-enabled speakers simultaneously.
