No sound on HDMI

[iditude]

Hello everyone,

I'm new to CentOS and I wanted to get my sound up an running. I'm facing some issues and I have reached a point where Google isn't helpful anymore. I have spent days trying to figure out how to do this.

Basically my sound card (VIA Technologies, Inc. VT8237A/VT8251 HDA Controller (rev 20)) works perfectly well through the first output (jack) but I can't get sound to go through HDMI.

aplay -l returns

**** List of PLAYBACK Hardware Devices ****
card 0: VT82xx [HDA VIA VT82xx], device 0: VT1708S Analog [VT1708S Analog]
Subdevices: 1/1

card 0: VT82xx [HDA VIA VT82xx], device 3: VT1708S Digital [VT1708S Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0

but even in root,

aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav

produces nothing.

I have tried alsamixer, I am not muted, etc. I don't know what I can do at this point. I have even tried ubuntu and fedora and I run into the same issue.

Thanks a lot for your help

Here is the output of the alsa info script, just in case that is useful : http://www.alsa-project.org/db/?f=43cb7 ... 1e08c7af51

It looks as if your HDMI device isn't detected.

Even when detected, it's a bit of a pain. I have a page about multimedia, with a few things about it.

http://srobb.net/dvds.html

There's a section on HDMI.

In a nutshell, with mplayer I specify the output device, if trying to do, say web videos or netflix one can either create a $HOME/.asoundrc file or, if using pulseaudio, use the GUI tools to specify output.

However, what I'm seeing from your output is that the HDMI device isn't recognized.
Running aplay - should have mentioned HDMI, e.g.

Code: Select all

card 0: Intel [HDA Intel], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Assuming pulseadio is installed, you can try installing pavucontrol and seeing if, after clicking the configuration tab, it's seeing an HDMI device.


Also, with Fedora and Ubuntu, did you get the same result with aplay -l, that of no HDMI device. (You can try with their live versions too, to save time, as well as Mint, which is often even better at hardware detetction)

Thanks. I never considered that my card wasn't recognised. Maybe it's badly recognised?

I tried Pavucontrol and I can see the HDMI output. I can change levels. However the sound icon above as a small "x" next to it (I'm not muted in alsamixer, but maybe there is another tool I can use?)

HDMI seems recognised when I run aplay -L

Thanks so much for your help

Hrrm, I haven't come across that--where aplay -l doesn't show it and aplay -L does. Did you install alsa-plugins-pulseaudio (or whatever it's called)? If so, if you use the pavucontrol, are you able to get rid of the mute?

Also, again using alsa-plugins-pulseaudio (if you're doing a small install--if you're using a standard Ubuntu, Mint, or Fedora, it is probably included), did you have better luck?

Thanks a lot for your help on this one.

I have exactly the same problem with Ubuntu 15.04, debian 8, Mint and CentOS.

This is driving me nuts... I have installed all the packages.

It's really weird as pavucontrol clearly has an HDMI audio output.

Thanks

Ok, sorry I can't be of more help. I would say try the Ubuntu forums as they would (probably) have the largest amount of users who work with multimedia. I only know the solutions I mentioned.

I had a similar problem and my solution was to set manually the audio output to "Digital Stereo (HDMI) Output" on System settings -> Multimedia -> Phonon -> Audio hardware Setup (TAB) -> profile

It is annoying that CentOS doesn't switch automatically between outputs when the HDMI connector is detected as it does with the screens.

You will need to select your "Analog Stereo Output" to use your speakers again.

Thanks to all. That didn't do it either.

No pb, I will investigate on the ubuntu side. Having the same problem with all distrib I tried, I fear this is related to the kernel.

Thanks again!

Cheers

You could test your assumption that the problem is kernel related by installing the kernel-ml package that is available from the ELRepo Project.

Hi everyone,

I have the same issue on my centOs (CentOS Linux release 7.1.1503 (Core))

I try to give you more informations as possible :

Code: Select all

lspci |grep -i aud

00:1b.0 Audio device: Intel Corporation C610/X99 series chipset HD Audio Controller (rev 05)
03:00.1 Audio device: NVIDIA Corporation Device 0fb0 (rev a1)

The wierd things is, if run

Code: Select all

 aplay -l 

:

I have 4 devices, maybe it's normal, I really don't know.

And in the phonon<audio hardware setup in harware profile I can switch between 4 profiles
-Digital stereo (HDMI) output
-Digital stereo (HDMI) output
-Digital surround 5.1 (HDMI) output
-Digital surround 5.1 (HDMI) output

Of course, I tried to switch between profiles but No sound on HDMI.

I tried to check if my card was muted but not at all.

Any ideas ? maybe a conflict issue ?

By advanced. Cheers !
