I'm trying to get HDMI audio on a Geforce GTS 450 to work on Centos
5.5. I have the latest NVidia binary drivers and ALSA 1.0.23.
Uner Windows 7, it just works as the default sound device after
installing NVidia drivers, so I know the card can do it. With ALSA I
don't get any devices at all:
aplay -l
shows no devices
but -L shows something:
aplay -L
front:CARD=NVidia
HDA NVidia
Front speakers
surround40:CARD=NVidia
HDA NVidia
4.0 Surround output to Front and Rear speakers
surround41:CARD=NVidia
HDA NVidia
4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=NVidia
HDA NVidia
5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=NVidia
HDA NVidia
5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=NVidia
HDA NVidia
7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
hdmi:CARD=NVidia
HDA NVidia
HDMI Audio Output
I have also an Audigy PCI card (emu10k1), the above output is with
that card disabled (only snd-hda-indel module loaded, no snd-emu10k1).
With both cards enabled, I get devices for emu10k1 (and it works).
Here is what I have is /proc:
/proc/asound/cards
0 [Audigy2 ]: Audigy2 - SB Audigy 2 ZS [SB0350]
SB Audigy 2 ZS [SB0350] (rev.4,
serial:0x20021102) at 0xb400, irq 66
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xe3ffc000 irq 177
/proc/asound/devices
0: [ 0] : control
1: : sequencer
4: [ 0- 0]: hardware dependent
6: [ 0- 2]: hardware dependent
8: [ 0- 0]: raw midi
9: [ 0- 1]: raw midi
10: [ 0- 2]: raw midi
11: [ 0- 3]: raw midi
16: [ 0- 0]: digital audio playback
18: [ 0- 2]: digital audio playback
19: [ 0- 3]: digital audio playback
20: [ 0- 4]: digital audio playback
24: [ 0- 0]: digital audio capture
25: [ 0- 1]: digital audio capture
26: [ 0- 2]: digital audio capture
28: [ 0- 4]: digital audio capture
32: [ 1] : control
33: : timer
36: [ 1- 0]: hardware dependent
37: [ 1- 1]: hardware dependent
38: [ 1- 2]: hardware dependent
39: [ 1- 3]: hardware dependent
So there are some devices for card 1, but they don't show up in aplay
-l and I can't play anything onto them.
snd_hda_intel is loaded, I don't have any special options for it. In
DMESG I get this:
hda_intel: Disable MSI for Nvidia chipset
but no error messages (or any other messages about hda_intel).
snd-hda-codec-nvhdmi is not loaded automatically. I can modprobe it,
it loads with no errors or messages, but nothing changes.
Can this card work under ALSA?
