Cannot get HDMI audio working in Sequoia & Sonoma.

Cannot get HDMI audio working in Sequoia & Sonoma.

Hi folks,

I am hoping someone might be able to help me with this. I have a Lenovo T14 Gen 1 running the new sequoia release and I have everything working with one exception, HDMI audio. I have the latest kexts and the latest opencore version. I have audio to the internal speakers and use bluetooth to connect to a soundbar with my gaming monitor Gigabyte M34WQ but I want to get the HDMI working as apple music will not play some audio tracks using bluetooth. I am aware of the workarounds for this but I want to try again to get my HDMI working. When the Hack was running sonoma I had the same issue. I've various layout Id's for ALC257 but none have worked.
