is everything set properly in the maudio control panel..? there is an ASIO box there, too...
fwiw - i use the standard waveout ap2496 spdifout option for foobar. no need for the asio here - and i havent heard a reason why its use would be preferable, as the ap2496 does not resample...
the asio is a big deal for cards that autoresample...
but i have got it to work, and iirc, it there is an asio switch in the maudio panel somewhere...

edit:
actually i think it is os/soundcard combo that nmakes the asio plugin the way to go. with win98, the waveout does the trick for me (directsound doesnt work so well with win98)...
but i have been running my config for years, so i havent messed with it in a very long time...
