I have Chromecast Audio connected to my SoundTouch Systems at the moment too.
The only suggestion I have is maybe to turn the volume up on your system. Sometimes, the audio is quieter on Chromecast/Bluetooth streaming.
I hope this helps

An earlier topic may answer the question. Whil the 1SR looks like it has an AUX input, it's a secondary connection for the primary input. Hence if you have TV connected you cannot switch to the second input. You may be better with a Chromecast attached to the TV.
