Beaglebone Ai autorun

Hi, everyone, new to the beaglebone Ai world and linux, so please be patient!

Need to autorun csound in an headless board, and not need the LXQT graphic frontend.
So, just boot the csound application (after all the other usual debian services) at power on.
I have already tried to use the (empty) ~/bash_profile but have no success.

Thanks for your attention.
