I'm not sure whether this code is whats being used to support the Pi HDMI ports but there is no question that Pi HDMI audio has been problematic for many years. Hopefully there will be some relief in Bookworm.
I'd like to see it work reliably up to 24/192, multichannel LPCM up to 7.1 and for passthrough Dolby AC3 and DTS bitstream. I think this is sort of whats expected from modern HDMI audio.
Yes, know that, what I was - sorry for not having explicitly said - referring to is the fact that it could depend on the hardware implementation too; that is, how things are done on the Pi; and if it is so, we may get it with the Pi5. Full support for HDMI would be such a great achievement.
