No sound from Google TTS in Sonos speakers

I’ve followed the set up of installing Google Cloud TTS and running this command in one of my rules:
say(“God morgon”, “googletts:svSEWavenetA”, “sonos:PLAY1:RINCON_B8E937E56C7801400”)

The rule runs without any errors in the Log and I’ve made sure that the same Sonos speaker is the default sink and tried running it with 100% volume but not a sound coming out of it.

Would be greatful for any insights on how to continue troubleshooting this.

Does speaking on other speakers work?

I also use the Google Cloud TTS and a similar configuration works for me.
