No.20565 Hydreigon Tester Sep 24, 2022, 03:30	Likely has to do with this: https://psx-spx.consoledev.net/konamisystem573/#konami-asic-registers "The exact purpose of bit 6 is unclear. Games use it to mute audio from the CD drive or digital I/O board; in particular, this bit is cleared during attract mode if attract mode sounds are disabled. However, testing on real hardware seems to suggest it is some sort of downmixing or attenuation control rather than a proper mute."

As mentioned, this is flagged as not working like a majority of other machines in the driver which supersedes all other flags including graphics and sound which are obviously not working right even in the machines which are producing sound.
