audio through HDMI on a IDT 92HD71B sound card

Dear all,

I have a Dell Latitude E6400 laptop, which has a Displayport. I tried to
connect the laptop with a Sony TV with a HDMI port. So I bought a
Displayport-HDMI converter from Dell. When I play a movie using mplayer,
the video is OK on TV, but without sound on TV. The sound is still played
by the Laptop. I doubt the sound card driver doesn't support HDMI, this is
the result of `aplay -l':
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0

This is the result of `aplay -L':
null
Discard all samples (playback) or generate zero samples (capture)
default:CARD=Intel
HDA Intel, STAC92xx Analog
Default Audio Device
front:CARD=Intel,DEV=0
HDA Intel, STAC92xx Analog

4.0 Surround output to Front and Rear speakers
surround41:CARD=Intel,DEV=0
HDA Intel, STAC92xx Analog
4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=Intel,DEV=0
HDA Intel, STAC92xx Analog
5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=Intel,DEV=0
HDA Intel, STAC92xx Analog
5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=Intel,DEV=0
HDA Intel, STAC92xx Analog
7.1 Surround output to Front, Center, Side, Rear and Woofer speakers

It seems no digit device. I tried both in Debian stable and testing. The
version of kernel in testing is 2.6.38, alsa is 1.0.23. Any suggestion?

Best regards,
Yuwen
