Thanks for your answer. I've just found sound expander's demodisk, but it
seems it does not produce sound under VICE either ...  Also, my data (which
is basically sequence of register numbers and datas including initialization
- with timing information included) works under DOSBOX with AdLib emulation:
it produces sound nicely.  I've just write a simple "player" to play this
sequence in x86 assembly for DOS and also for C64, but the latter does not
work.  But since the "official" demo disk for the cartridge does not produce
sound in VICE either (yes, VICE is configured correctly for the cartridge
emulation), it seems to be an emulator issue, at least IMHO.

So I guess it can be an emulator issue ... Unfortunately I have no idea how
to get the real hardware (the cartridge) to test it on a real machine ...
