How play a loop of siren sound with a buzzer

ESPHome
1

Hello everyone, I am an EspHome newbie.
I have created a project that uses an MQ-2 sensor and three LEDS, a green one that power on when the gas values are normal, a yellow one that lights up when the gas values are in an alert range and a red one when the gas values are dangerous.
In the latter case, the project also includes a buzzer sound.
I have managed to program the automations in esphome to do all this, the only thing I cannot do is the continuous buzzer sound.
At the moment it sounds for a few seconds and then stops, I would like it to sound for as long as the red led is on.
Another problem is that the volume of buzz is low, how I can up it?
Can you help me with this.
I paste the code I have created:
