could work. but maybe some numbers identifying sliders or output mixers don't
fit us224. we would need info from tasam or usb snooping windoze or
braveheartedly testing on linux to know more.....
...also i'm not completely shure if the snd-usb-usx2y's mmap interface is
initialized for us224 also. us428control talks to the driver with it.
Just give it a try.

No sound on playback.

You uncommented any section containing USB_ID_US224 in snd-usb-usx2y?
Also for trying on us224 please change
usbusx2yaudio.c line 1244
(usX2Y(card)->chip.dev->descriptor.idProduct == USB_ID_US428 &&
to
(usX2Y(card)->chip.dev->descriptor.idProduct == USB_ID_US224 &&
have fun,
Karsten
