nVidia HDMI Audio


I just installed Slackware 13.37 on my desktop and I went to nVidia's website and downloaded the driver for my Geforce GT 430. The driver works for video but there is no sound. I have tried to configure Alsa but i dont know how to get the nVIdia card to be the default audio output. Im losin my mind with no sound is anyone familiar with this problem??

it looks like your nvidia card is occupying sound card slot 1, but if you want it to be your default sound device it needs to be in slot 0, see this post for more details.

I'm using the same graphics card on my HTPC. I'm currently within seconds of passing out or I'd get out of bed and check it for you, but I had to adjust a setting somewhere in my sound preferences. I had to make sure the HDMI options were selected, but even then I had no audio. Under either the Hardware or Output tab, I had quite a few selections there. I recall seeing a few that ended with nr#. I remember seeing nr2, nr3, nr4, etc. I think nr4 was what worked for me. What is it? I have no idea. I realized only one out of the bunch worked. When you find those options, try each one while playing an audio file, once you hit it within 1-2 seconds the audio should kick on.

For what it's worth, I'm using Ubuntu 11.10 on this HTPC with the GT430. Good luck.

This is what I did to get audio over HDMI to work on my computer (inspired by this thread):
  1. Run
    Code:
    sudo killall pulseaudio
  2. Run
    Code:
    alsamixer
  3. Press F6 and choose "1 HDA NVidia".
  4. Unmute all SPDIF.
  5. Change line 44 & 45 in /etc/pulse/default.pa by decomment and change:
    Code:
    load-module module-alsa-sink
    load-module module-alsa-source device=hw:1,7
  6. (KDE specific) Open the mixer by clicking on the volume control in the lower right corner.
  7. (KDE specific) Choose Settings > Audio Setup
  8. (KDE specific) For "Music" & "Video": Enable in "Show advanced devices" and move "HDA NVidia (HDMI 0) #7" up to the top of the list.

Then it worked for me!

Because the audio signal passes through the video card, and nouveau HDMI audio support for the 4XX nVidia cards only dates back to decemeber 2011-

Nouveau Commits: Fermi Reclocking, PM, MXM, Etc
Posted by Michael Larabel on December 19, 2011

Here are some of the interesting commits that landed last week into the public Nouveau kernel driver tree.

- HDMI audio support for NVA3 through NVD0 chipsets (commit). This HDMI audio support is for graphics cards from the GeForce GT 240 through some GeForce 400/500 "Fermi" GPUs.

Thanks to Stephen Warren at nVidia.

ftp://download.nvidia.com/XFree86/gp...dmi-audio.html

Quote:
This document attempts to describe everything you need to know about configuring audio-over-HDMI on recent NVIDIA GPUs and chipsets. A fair level of detail is provided, in an attempt to fully explain everything, rather than hiding useful details.

For brevity, the phrase GPU below includes both GPUs on standalone graphics cards, and GPUs integrated within chipsets. The phrase GPU specifically covers only NVIDIA GPUs, and never includes GPUs from other manufacturers. In some cases, chipsets and GPUs may be explicitly discussed separately due to differing feature sets.

For brevity, this document discusses HDMI audio. However, everything herein applies equally to Display Port, and in many cases also DVI ports when connected to an HDMI port on the display device.

The references to a "monitor" within this document apply equally to any device capable of receiving an HDMI signal containing an audio signal. In particular, an A/V receiver with an HDMI input may be used to receive the HDMI signal, process just the audio portion of the signal, and either ignore the video portion completely, or pass that video on to a display device.
