OK, now that we have the Chromecast Audio, here's the NEXT thing we need!
The CCA is a handy little device for all of those powered speakers -- which is nearly all of them -- that don't have HDMI inputs. And while some apps like Google Music, Spotify, and TuneIn already support casting audio, one class of app is MIA: Android alarm clock apps.
Currently I stream my favorite alarm clock app via Bluetooth to a set of powered speakers to which is connected a Bluetooth receiver, and while that mostly works fine, I'd rather bypass my phone as an audio intermediary and just have the streaming content go to the speakers directly from the source.
The only minus I can think of is that most "clock radio" apps can detect when a chosen source is offline and then play an annoying alarm to awaken you, but it shouldn't take rocket science to account for that situation.
So c'mon, +Apalon
, +AVG Technologies
, and all you other talented developers, and update those alarm clock apps!
