The patches referred to in the git issue are for alsa and would be independent of the kernel however there was no resolution of the issue yet so still open.
Over the years I've never seen a concrete solution to HDMI audio on the Pi. It always seems to have bit-depth or sample-rate issues. I can see in the kernel hdmi driver there is support for 24-bit audio but its a very complex driver and so not clear to me what has to be present in PCM frames output by ALSA to green light 24 bit. https://github.com/raspberrypi/linux/blo...deo/hdmi.c
