Try the module options listed in the xbmc wiki for these cards:

After a bit of experimentation, modifying modprobe.conf with:
options snd-hda-intel enable_msi=0 probe_mask=0xffff,0xfff2
got rid of the extra devices:
$aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC883 Analog [ALC883 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC883 Digital [ALC883 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI]

When loading the snd_hda_intel driver there is a delay and a series of
messages like:
ALSA hda_intel.c:1420: Codec #1 probe error; disabling it...
I was able to get sound out successfully. Mplayer output digital sound
flawlessly for the six or eight files I tested. Myth's internal player,
however, had broken and stuttering sound. I suspect this is an issue
with the .asoundrc file I used (not used by mplayer), which was copied
from an Asus Revo I have in another room. I need to experiment more.
The other issue I have is I am only getting 2-channel output. Loading
the driver displays these messages:
HDMI hot plug event: Pin=5 Presence_Detect=1 ELD_Valid=0
HDMI hot plug event: Pin=5 Presence_Detect=1 ELD_Valid=1
HDMI: detected monitor FPD TV
at connection type HDMI
HDMI: available speakers: FL/FR
HDMI: supports coding type LPCM: channels = 2, rates = 44100 48000
88200, bits = 16 20
Even though it is connected to a 5.1 receiver. Playing a 6-channel test
file or using speaker-test -c6 I only get sound out of the front left
and right channels. The XBMC page Michael pointed out seems to hint this
is an issue with other GT-220 cards. I might need to wait for another
ALSA update.
