Don't estimate a breakage version. You can give an estimate in your description or additional information, but do not fill in Regression Version unless you have tested and can firmly say something has been broken then.
That said, I flagged the whole driver for audio issues as most games (gameboy, gbcolor and even some gba games) have an issue with mis-pitched sound.
The idea was to avoid reports, but I'll accept this as a catch all for all sound reports for gameboy drivers.

Unknown when it will be fixed.

There seems to be a difference between gameboy and gbcolor as well. A good testcase is the intro music in zeldaldx:

Sounds correct:
mame gameboy zeldaldx

Sounds wrong:
mame gbcolor zeldaldx

By contrast, zeldalnk sounds OK in both drivers.

It looks like this is fixed now. Both the reported kungfu and 'mame gbcolor zeldaldx' sound okay.
