On 13 pro max after the latest update 27.0.1 the volume is lower after summoning Siri while conducted via the aux adaptor. For example I can listen to my music at max volume from my phone and at level 7 on my car and after summoning Siri I have to increase the volume to eg 18. The problem is solved after restarting the phone but it returns after saying hey siri or summoning it via the button.
