Sound on HMDI AND 3.5 mm jack


I have a little problem with my M3 + Android and the audio output. I am not sure if it is a M3 thing at all or just a Android settings behaviour.

Anytime I put a plug into the 3.5 mm jack M3/Android mutes the sound on my HDMI-output. But I like to get it over HDMI and parallel over 3.5mm. I could’nt find annything in the (very simple) settings of my android regarding audio outputs at all. It is possible to get the Sound over both connections?

thanking you in anticipation

Good morning! Practically every time I had been using writing help company while studying at high school. One of my English language teachers asked me to write a huge school letter. Mostly, I hated these types of work, so I prefered to pay money for it. And now I am using pretty cool online writing company that helps me a lot with all of my no so simple writings.
