    Onboard HDMI Audio Doesn't Work

    I'm running Ubuntu 10.10 with an EVGA nForce 730i Intel mobo with onboard HDMI. Video output works. Audio output does not. I'm trying to output both to a Samsung HDTV.

    I tried booting to a bootable drive with Ubuntu 11.04, and no audio.

    I've essentially tried everything in every other thread. I'm using alsa mixer, I've muted S/PDIF, my settings all have HDMI output selected.

    sudo modprobe snd-hda-codec-nvhdmi results in:
    Code:
    WARNING: /etc/modprobe.d/alsa-base.conf line 42: ignoring bad line starting with 'sudo'
    WARNING: /etc/modprobe.d/sound.conf line 1: ignoring bad line starting with 'enable_msi=0'
    WARNING: /etc/modprobe.d/sound.conf line 2: ignoring bad line starting with 'probe_mask=2'
    Which disturbs me a bit. I've messed a bit with the configuration, clearly.

    aplay -l results in:

    Also tried aplay -D to play a .wav, and heard no sound, but also encountered no errors.

    I'm stumped

    Re: Onboard HDMI Audio Doesn't Work

    Your changes especially to probe_mask possibly just hides the problem..
    I suggest you edit the /etc/modprobe.d/alsa-base.conf & comment out or delete the line 42.
    There should not be any "sudo" in there.

    I think you should edit the /etc/modprobe.d/sound.conf & remove the probe_mask.

    Then you must run
    [sudo] update_initramfs -u
    & then reboot..

    Then repost the aplay results again..

    The last line in that is 42, which I commented out. I thought I already had. Not even sure what I was trying to do with that exactly originally.

    sound.conf:
    Code:
    enable_msi=0
    # probe_mask=2

    Re: Onboard HDMI Audio Doesn't Work

    And you did run
    update_initramfs -u
    & rebooted ?

    The probe_mask value of (2) would expose only physical codec #3 to alsa/pulse.
    That may not be wrong exactly..

    Does this make any noise ?
    speaker-test -c 2 -r 48000 -D hw:0,3
    speaker-test -c 2 -r 44100 -D hw:0,3


    The original HDMI audio soundcard/codecs do not report the ELD data for the attached HDMI device so the audio output format can be incompatible..

    & what does this return ?
    cat /proc/asound/card0/codec#3

    Re: Onboard HDMI Audio Doesn't Work

    both speaker-test calls resulted in no audio

    Re: Onboard HDMI Audio Doesn't Work

    The old HDMI audio h/w does report the attached device ELD properly/at all.

    Try these lines...
    speaker-test -c 2 -r 48000 -D iec958:CARD=NVidia,DEV=0
    speaker-test -c 2 -r 48000 -D hdmi:CARD=NVidia,DEV=0

    The "sudo blah blah" in the alsa-base.conf was a terminal command to copy some text into the alsa-base.conf file without using any editor.
    I don't think that will help with HDMI audio at all.

    The /etc/modprobe.d/sound.conf was incorrectly formatted
    if it was needed it might be
    options snd-hda-intel enable_msi=0 probe_mask=2
    BUT you do not need this ...certainly not the probe_mask bit..

    Still no sound with the speaker-test commands

    Re: Onboard HDMI Audio Doesn't Work

    HDMI Audio on NVidia MCP7A
    In the case where multiple HDMI display connectors are present, the audio stream is broadcast to all HDMI connectors at once.

    ELD and PD information is not available on these chipsets.


    In these chipsets, the multiple 2-channel converters are aggregated by the ALSA driver and exposed as a single 8-channel device. Some chipsets support 2, or 8 channels (MCP77). Other chipsets support 2, 6, or 8 channels (MCP79).
    Don't know how to use this info really..
    but 2 ch should have worked..

    So give up & admit defeat..
    HDMI audio with this chipset was working in 2008 alsa 1.0.18

    Are you using any odd settings in /etc/X11/xorg.conf like option "UseEDID" "False" ?
    Do you have any BIOS settings for HDMI audio/HDA intel ?

    Do you have a BIOS setting for iGPU RAM allocation ? if yes try automatic..
