Intel HDMI sound not working

Bio · Posted: Sun Jun 07, 2009 10:07 am Post subject: Intel HDMI sound not working

Hello,

I've been trying to have my sound working through HDMI with no luck.

My motherboard is an Asus P5E-V HDMI with a G35 chipset. The built-in video card offers an HDMI output.

I just upgraded to kernel 2.6.29-r5 and noticed that the Intel HDMI driver was finally available so I tried that but couldn't find a way to have the sound working with HDMI.

Any clue?

For reference

Are you sure it's not an Analog Device audio chipset? I had to enable that (as
well as the Intel stuff) in order to get audio on my P5 board, but it's a different
code number and may be using a different chipset.

From the output of your aplay -l command it looks like it should work.

Have you tried sending output specifically to the HDMI device, e.g
mplayer -ao alsa:device=hw=0.3 some_audo_file
The HDMI out on my media centre box doesn't seem to get sound by default, unless I specifcally instruct alsa to send it there.

edit: also, make sure you're running the application you're using to play audio from an X session outputting to the HDMI device you want to hear the sound on. Sound doesn't seem to work for me otherwise.

also, check for a bios upgrade. I have a board that had no sound via HDMI untill after that.

So far no luck, could it be related to my alsa-utils version? 1.0.17

I thought about upgrading the BIOS but that means installing a Windows OS since I don't believe ASUS provides a flash utility for Linux. As this box is my file and backup server I will keep this idea as last resort.

It took me a while to realize that the X server has to be running.
I made all my tests from the console, thinking that i would try to get the display running correctly afterwise.
I got bored of working on sound, thought that i would see how the video playback was working.. and i got sound.

Did you made your tries from the console or from a X session?

Just out of curiosity, did you unmute your card? From the Alsa-sound-mini-HOWTO:

strange as it seems, its not playing kde system sounds.

I ended up doing the following before I figured that kde was part of my problem, somewhere along the way it fixed it.

I set the kernel to load modules, then I was able to run alsaconf and it saw my card correctly, I also had to start alsasound service. I went back later to kernel compiled in drivers and those appeared to work. At one point after all that I popped on the internet to play a youtube video and discovered the sound was actually working! No i have to figure out why kde wont play system sounds.
