There is a bug in Windows 9x that prevents sndvol from seeing more than one
topology port in a single PNP device node. I raised this with Microsoft
several years ago and the only solution seemed to be to create a bus driver
for the card and then one child driver for each subdevice. I used the bus
driver example in Walter Oney's book as the basis for this and eventually
got it working.
