Delete sound in Google Home (media player) when turn on

When I turn on my HA from Google, it generates a sound. This sound is sometimes annoying when I use TTS because it cuts the first word.

I have looked at the configuration of the Google Home device and there is nothing about that sound, so I think it is generated by HA.

Does anyone know how to remove that sound?

Thank you

This is worth a read I did it. I defeated the horrible Google Home "cast-start" prompt sound!

Oh! Thank you very much, I did not know how to look for that information. I’m going to try it, although there seems to be no solution for the Google Home groups.

Thank you
