It looks like HDMI audio stopped working in 5.17-rc1. I ran a bisect which points to 636110411ca726f19ef8e87b0be51bb9a4cdef06. I built 5.17.14 with it reverted and it restored HDMI output, but it doesn't revert cleanly from 5.18 onward. >From what I can tell it looks like -ENOTSUPP is returned from snd_soc_dai_set_stream for hdmi1 and hdmi2 now. I'm not sure if that's expected, but I made the following change and I have working HDMI audio now. https://gist.github.com/jmontleon/4780154c309f956d97ca9a304a00da3f Thank you, Jason Montleon
