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':

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
