Good news, the issue is now officially resolved by ASUS.

ASUS released new BIOS versions for the motherboards I had reported to them:

- ROG STRIX Z790-F GAMING WIFI: BIOS 3201
- ROG STRIX B660-F GAMING WIFI: BIOS 4001

ASUS support clarified that the feature is present but not enabled by default.

To make the PC Speaker work correctly, you need to enable the following option
in the BIOS:

"BIOS" > "Advanced Mode" > "Advanced" > "Onboard Devices Configuration" > "8254
timer clock in OS"

After enabling this option on the Z790-F with BIOS 3201, I can confirm that the
PC Speaker works correctly again.

Unfortunately, I cannot test the B660-F at the moment, but since the same
change was reported for its BIOS as well, it should behave the same.

It's currently not clear whether this fix will be released for other
motherboards too. If you are affected, it's worth checking whether a BIOS
update is available for your motherboard and then looking in the BIOS for the
option "8254 timer clock in OS" (or something similar).

If you can't find it, I recommend contacting your motherboard vendor's support
and mentioning the issue, as well as the fact that ASUS solved it by
introducing this BIOS option. That may help them reproduce the fix on their
side.

Huge thanks to ASUS support and their technical team for actually investigating
the issue and implementing a fix. The support experience was genuinely
impressive.
