Audio HDMI with touch screen PI4


I have a problem with my HA setup.(2022.9.6)
It is running on PI4, debian 11 in docker, with touch screen connected to HDMI_0 port. the speakers are embedded and connected to HDMI_0 too.

speakers are working fine until the HA containers start.
I have no sounds going out.

Do you have any idea what I could do to get sound through HDMI with HA ?
