I have just tested it in my set-up to check as a comparison. I have multiple Chromecast Audios set-up and Astiga is playing audio direct to those in the Android app without a problem.
It should play to all Google Cast devices. At least here my Google Home and Chromecast Audio are showing up. It might sometimes take a few seconds before it finds all available Google Cast devices though.

OK. Thanks for the answers. Good to know that it should work. Tonight I'll give it a try.
