Should be some commits between the following. Before these commits, the HDMI audio can at least been identified but needs to be manually switched.

Later the bug was fixed and definitely not present in 5.19 However, this bug is present in 6.x kernels included in Lunar and Mantic as well as in 6.5.7-060507.202310102154 Currently I rolled back to 5.19 to confirm that this issue is fixed in this kernel.
