No HDMI Audio with Intel HDAudio

[ChrisTomalty]

While HDMI audio-out has never worked on my Dell Inspiron 1525 with an Intel's HD Audio card, I expected it to work in Karmic after updates to the sound infrastructure.

I am running Ubuntu 9.10 Alpha 4 64 bit patched as of 13:20 22/08/09.

It is a Dell Inspiron 1525 with Intel HD Audio, a Core2Duo processor, and 4GB of RAM

Have you installed pavucontrol and selected the appropriate profile?

[ChrisTomalty (christomalty-deactivatedaccount)]

No. I never knew I had to... I will test it now...

Shouldn't that package be installed by default if it's required for such functionality (where the normal user will expect it to just work, plug 'n play?)

It's not required for _all_ hardware.

[ChrisTomalty (christomalty-deactivatedaccount)]

Ok - tested it with pavucontrol installed. No change, even when using pavucontrol instead of the default audio control.

I tried both HDMI Audio output options. If you need me to run any commands, just tell me...

[ChrisTomalty (christomalty-deactivatedaccount)]

For the record: the device I'm trying to output to in a Samsung HDTV (though the Displays manager only recognizes it as a 7", which I think is due to graphics card limitations

[Luke Yelavich (themuso)]

Could you please download http://www.alsa-project.org/alsa-info.sh and run it, then attach the resulting file that is created? This will likst more information about your hardware to try and help determine whether alsa is correctly identifying your HDMI hardware.

Thanks

I have a DELL Inspiron 1525, and the sound does not work when you connect mi laptop to the TV for HDMI

I've tried a thousand ways and nothing.

It's pantalla of aplay -l:

[Brad Figg (brad-figg)]

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p alsa-base 417428

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I'm trying to use my wife's laptop to watch movies and TV Shows on my LCD TV.
I'm using a fresh install of Ubuntu 10.04 Lucid Lynx.
My wife always used the Windows Vista (came with laptop) to watch videos, but the Windows Vista was not handling well (performance issues) the high definition videos. So I convinced her to make a dual boot on laptop using Ubuntu.

Laptop is D'ell Inspiron 1525 laptop and the TV is a Samsung LCD TV 26".

There is no audio when I plug the HDMI cable. I have tried a bunch of attempts to configure the audio output (searching on Google), but none of it works. Even when I try to run 'speaker-test' there is no audio at all.

I'm very pleased if someone can help to figure out what is wrong.

>>>> Follow the output of my configuration:

You can turn off the computer and restart and maybe the sound is activated, which should not happen. The normal thing would you connected the hdmi, select that output and functions. What other stories are not sleeping and therefore this is a bug user-facing enormous.

Hi,
I have exactly the same problem with a Dell 1525N. I can only watch the movie but I cannot heard any sound from the TV with the HDMI link.
I use Ubuntu Lucid and I have try to update Alsa to 1.0.23 (instead of 1.0.22).

[Iuri Diniz (iuridiniz)]

no problem with me on Lucid and I have a Dell 1525 too, How are you
selecting the HDMI output?

I pretty sure you have HDMI configured:

'hdmi:CARD=Intel,DEV=0
   HDA Intel, INTEL HDMI
   HDMI Audio Output'
