I bought the correct Samsung-branded USB-C to HDMI cable in order to mirror my phone screen and audio on the TV at my AirBnB while on holiday. I used this successfully on both my Galaxy Note 10 and my Galaxy Note 8 - audio and video both worked. That TV was a Smart TV, but not a Samsung. Now I'm back home with my non-smart TV, and the cable works fine with my Note 10, but I can't get audio from my Note 8. The screen mirrors fine, but when the HDMI cable is connected, there is no audio from either the TV or the phone itself. When I switch to Samsung Dex, the audio does come through the phone, but not through the TV. The problem is that I can't resize the app to fullscreen when using Samsung Dex, so I'd rather just use screen mirroring. Any solution as to how I can get the audio to work? Thanks.
