yes, you have old kixtart version.
however, your old code should have worked and if it didn't beep, you should check again that it actually ran at all.
the code was written in such a manner that it always outputs something and sleeps a bit.
so if you can't get anything to the console with it, you are not actually running it.
anyway, you could start by upgrading your kixtart to at least 4.22
