HDMI audio device detected by the system but not listed in Sound Settings

Bug Description

It is certainly just a graphical matter because using hardinfo, running pacmd or trying to switch to HDMI in XBMC works, it's just not listed in System Settings -> Sound.
From the screenshot you can easily verify there is no HDMI output listed.
This is a regression from Oneiric, which correctly shows all the available hardware outputs on the same computer.

This is the same window on the same computer using Oneiric, it's very easy to switch to Digital Stereo (HDMI) Output.

A restart fixed it ?

David Henningsson (diwic) wrote :


An improvement from Oneiric is that the HDMI output should not be listed if HDMI audio output does not currently work, so it is only a regression if HDMI audio output in fact works, but it is not listed.

Could you verify that you have activated your secondary monitor and that HDMI audio works, and then submit the output of "pacmd ls" and an alsa-info according to https://wiki.ubuntu.com/Audio/AlsaInfo ?


Leuke (leuke) wrote :

I understand the intentions, but I'm fairly sure that is not my case because I tried HDMI output using XBMC's own sound manager and it worked perfectly.
As requested this is the output of "pacmd ls".

Leuke (leuke) wrote :

And this is the alsa-info file.
Hope they help!

David Henningsson (diwic) wrote :

Yes, they are helpful. It seems you have HDMI profiles but not ports, because your driver does not create any jacks.

Could you try to edit this file:


and change this line

required-any = any


required-any = ignore

Restart pulseaudio (e g "pulseaudio -k", or restart your computer) for the changes to take effect.

Please report back if this resolved your problem. Thanks!

Leuke (leuke) wrote :

I modified that line and then tried both restarting pulseaudio and the entire system, but that didn't resolve.
I noticed that there are several hdmi-output-x.conf files, so then I tried to modify all of them (from 0 to 3) as you suggested and restarted the computer again.
Nevertheless I can't yet see HDMI output in Sound Settings, that menu hasn't changed at all.

Maybe not relevant but in addition to XBMC also vlc is able to correctly detect HDMI.

David Henningsson (diwic) wrote :

Ok, strange. Could you provide a pulseaudio verbose log according to https://wiki.ubuntu.com/PulseAudio/Log ?

This should be with the required-any set to ignore.


Leuke (leuke) wrote :

Here it is. This is the output file with "required-any = ignore" in "hdmi-output-0.conf".

David Henningsson (diwic) wrote :

Aha. I think it should be

required = ignore

instead of

required-any = ignore

I should probably fix PulseAudio to make "required-any = ignore" work as well here.

Leuke (leuke) wrote :

Now it works, thank you!
Just a consideration: "required = ignore" completely fixes the problem for this system (it's a Nvidia ION netbook).

On the contrary, on another computer ( AMD graphics desktop, open source drivers) this is the situation:
    - default : hdmi not detected and not working.
    - required = ignore : hdmi not detected and not working
    - required-any = ignore : hdmi detected but not working

So, ignoring the fact HDMI audio isn't working while it should (this is not strictly related to this bug), the first and the second behaviors are what we would expect, while the third shows an option detected but not effectively available.
This is the reason of the change from oneiric to precise, right?

I have the same problem on my 4 amd/ati card multiseat setup. But I get one card listed, I tried all combo's of this and none work.

gavin (gavinewin) wrote :

Not sure if I have the right topic here, but it sounds similar. I have a Acer I7 Nvidia Optimus notebook. When I plug in a HDMI monitor, I can go to sound settings and select HDMI output which deselects built in audio. Everyting works fine. However, when I take the notebook out (not plugged into the second monitor) and even after a full restart, I have no sounds, I have to go back into sound settings and select built in audio, even though it is the only sound option available. Shouldn't this be selected automatically on a reboot if it is the only sound output available?

This indicates that you don't have your HDMI cable plugged in. Or possibly, that there is a problem with your video drivers detecting that you have actually plugged it in.
That's why it doesn't show up. Are you sure it works? If it does not work, the sound settings is doing the correct thing by hiding stuff that doesn't work anyway.

So i have 3 hdmi devices. (btw cable was plugged in). The only one which works is:

Any ideas?

David Henningsson (diwic) wrote :

@Andrei, ok, then that's the first I've heard of with working audio but broken jack detection.

> Any ideas?

Most likely the problem is on the video driver side. Are you using proprietary NVidia drivers or Nouveau drivers?

Andrei Gherzan (andrei-7i) wrote :

proprietary NVidia . But these are the same used in 11.10. And there the bug is not replicated.

I think I may have a similar problem, but the information in the previous comments didn't help. My AlsaInfo is at http://www.alsa-project.org/db/?f=6a2f2ceebd41031845175e0fe59b5d8f2477a510

I also put some screenshots and more information in a thread at http://ubuntuforums.org/showthread.php?t=2013831.

Since the issues appeared to be similar, I added the information here first. Let me know if I should create a different bug report.

Aaron Gerber (agerber85) wrote :

Same here. HDMI video output becomes available automatically when hooked up, but HDMI sound output does not. (It is not listed in Sound Settings dialog.)

My machine has not proprietary drivers installed, so that can't be the source of the problem.

If I restart pulseaudio while HDMI is hooked up, the HDMI sound output becomes available. Essentially, the list of available outputs is not being refreshed automatically.

My pulseaudio is version 1:1.1-0ubuntu15.

Hi Leuke, do you know when it showed up in Raring again, if it was related to any specific version of Linux kernel or possibly version of nvidia binary drivers?

Leuke (leuke) wrote :

Not exactly, but I just downloaded some packages from kernel.ubuntu.com/~kernel-ppa/mainline/ and I found out that this behavior started with linux 3.6.0.
When I downgrade to linux 3.5.7 I can choose HDMI without problems.

6.1.2. Chipset with 8-channel support, single stream

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).
