[alsa-devel] Trying to figure out what went wrong with my HDMI.

I have a M3N78 Pro motherboard, and am running alsa 1.0.18a on it.

I had HDMI audio working on it, but for some reason it has stopped.  I
really didn't change too much about the computer, other then take out a
hvr-1800, and put in a hvr-1600.   I did try to go up to .27 kernel, but had
other problems and went back to .26.   Recompiled alsa 1.0.18a and even
tried multiple versions of the nvidia drivers.  (173, 177)..     And now I
have just tried the snapshot with the same results.

I believe it was recognised as a ALC883 before, and not is is a ALC1200, but
I'm not completely sure about it.

Help!  :)


aplay -l shows:

card 0: NVidia [HDA NVidia], device 0: ALC1200 Analog [ALC1200 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 1: ALC1200 Digital [ALC1200 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

So, everything looks good there.

If I try and do an aplay, I get.

#aplay -D hw:0,3 /usr/share/sounds/alsa/Noise.wav
Playing WAVE '/usr/share/sounds/alsa/Noise.wav' : Signed 16 bit Little
Endian, Rate 48000 Hz, Mono
aplay: set_params:966: Channels count non available

I noticed that I am missing hdmi in my aplay -L.   When it worked, it was

# aplay -L
