Pulseaudio and media folder Homeassistant Supervised

I installed Homeassistant supervised on raspberrypi 4 running on Debian 11.

Please guide how to solve the following issues:-

  1. How do I autostart pulseaudio and connect to bluetooth? I have already installed pulseaudio and I am able to connect to bluetooth speaker manually via the terminal.

It is possible to autostart pulseaudio and connect to bluetooth speaker automatically once the homeassistant is started?

  1. How can I change the default media path?

Kindly guide.
