[Alsa-user] Nvidia ION HDMI soundcard

[José L. S. L. <jos...@gm...>]

Good afternoon!

I'm a "Debian unstable" user, using the latest Alsa packaged version.
With that version, I was able to play sounds through my integrated
Intel sound card, but I wasn't to use the HDMI sound capabilities.

My "aplay -l" output could help:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC888 Analog [ALC888 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC888 Digital [ALC888 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I'm trying to activate the audio support of my Nvidia Ion graphic card,
and I compile alsa-driver from the latest snapshot. I compile and
install it using:

$ ./configure.sh; make;
$ sudo make install

After the installation and reboot, my aplay -l output changes to that:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC888 Analog [ALC888 Analog]
  Subdevices: 1/1

As you can see, the HDMI audio devices are working. On alsamixer I can
see 4 IEC958 switches, but I tried enabling them all and I can't get
audio from the HDMI.

Can anybody help me? Thanks a lot.

P.S. If you need another command output, dmesg or any other stuff, let
me know.
