hdmi lightning accessory - audio not working after iOS 16 update

I’ve been using the hdmi lightning accessory to connect my iPhone 13 Pro Max to my tv to watch crave tv and Netflix. Im doing it this way so that I can stream at a lower quality and use less data. This was working flawlessly until I updated to iOS 16. Now when I connect the video works but there is no audio. I have tried doing a soft reset on my phone, removing the apps and reinstalling them, adjusting sound on my phone and nothing has solved the issue. Funny thing is when I connect to the tv and play a video on apple fitness there is no issue with audio. Anyone else having this issue?? Help?!
