Volume set Sonos isn't working

Configuration
1

Hello HAS,

I setup my Synology Home Assistant for auto turn on-off a light and to let the dog bark when there is movement. I need help with this last part, the dog barks but the volume level doesn’t work.

What I would like it to do is the following, the Dog volume to the max, after the mp3 is finished the dog volume back to normal and return to radio station before the dog bark.

Any help is appreciated.
