A year ago, there was an intriguing post to the Raspberry Pi Forum: "The development kernel does allow you to have HDMI audio on both ports at the same time. You'll have to wait for it to be pushed to general release via an apt update."
That ALSA still reports only one HDMI audio port suggests this push hasn't occurred yet but I haven't been following the issue and in any case I don't have any HDMI-based audio gear with which to test.
Even if only one HDMI port supports audio it would seem the other port could be used for display since folks have been running dual monitors on RPi4Bs since last year.
