Mute/Unmute that speaker which is playing an Advertisement

1

Hello Everyone,

I have few Chromecast speakers which are placed in different rooms. I play a stream from internet on these speakers. The stream plays an advertisement at random times. I use the below automation/script to mute the speaker when the advertisement starts to play and once the advertisement is finished the speaker is unmuted. The script works fine.

Is there a way to make the script generalised so that it checks which speaker or speakers is playing the advertisement and mute/unmute only that speaker or speakers?

Please guide.
