Have you tried the ALSA:hw:c,d format? Where c is the card number
(usually 0), and d is the device. It has been a while since I looked at
devices, but I think nforce and intel are 2 and emu10k1 is 4 (or was it
0?). What is the output of 'cat /proc/asound/devices' ? Perhaps
compare which device number the two cards are using for digital playback
(unfortunately they usually list more than one).
You can also use ALSA:plughw:c,d if you sample rates don't match.
