Linux+Nvidia HDMI = no sound?

hiberphoptik · #1 7th April 2008, 09:03 AM

Is it even possible to get sound out from an HDMI port in linux?

machine is a HP dv9000 laptop with nvidia card, HDMI video works great but how do you get sound to pipe thru that sucker?

Word off the street is that the newest nvidia driver now supports audio over hdmi.

cpelliott · #3 4th August 2008, 04:51 PM

Anyone have audio over HDMI working now? I have a HP DV6700T running F9 and don't see an audio option for HDMI. My video is working fine over HDMI with the nvidia driver from livna. The sound preferences gives me

HDA Intel (Alsa mixer)
Realtek ALC268 (OSS Mixer)
ALSA PCM on front:0 (ALC268 Analog) via DMA (PulseAudio Mixer)

Some hardware info:
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
01:00.0 VGA compatible controller: nVidia Corporation GeForce 8400M GS (rev a1)

Same thing here.

HDMI great, but without sound.

Will post further info.

After reading a thread on nvnews, theres a quote that confuses me:

Quote:

you can not get the gpu to pass along the audio through the hdmi

So now i'm not sure if HDMI should pass the audio along or not ?

Do you have other digital sound output from your lappy?

M4rc0 · #6 10th August 2008, 02:08 PM

Yeah i have double audio-outputs. But that's normal, it's for headsets.

So i bought a normal RCA cable, the one with red and white on the other end. Connected on my tv but no sound D:

It's the tv problem tho, maybe because it can't "use" both hdmi and those audio modes at the same time.

Then i connected some good pc stereo boxes with this cable, and it worked.

Too bad but it's a good alternative

If anybody gets sound with hdmi, share here with us!

marcrblevins · #7 10th August 2008, 09:45 PM

Then those are not digital audio ports. If you look at a SoundBlaster brand sound card, you would noticed amber color(darker yellow) audio port is the digital port.

M4rc0 · #8 18th August 2008, 04:40 PM

Sorry, it appears i lost the notification of this topic

Sure, now i get what you mean.
But i don't necessarily need digital audio ports?

Shouldn't this sound output work on the tv with the RCA anyway?
How come it worked with pc stereos...

It is a tv issue, right?

I've read a lot of posts, that confirm that hdmi audio is working with nvidia drivers 173.14.12 and newer.

I'm currently with ubuntu 8.10 with nvidia 177.80, with alsa drivers from realtek "realtek-linux-audiopack-5.07", but I can't get hdmi audio working. I have an asus g1s.

People who got it work, usually on a desktop and the aplay -l mentions something about "digital audio" or "hdmi audio".

Here's my aplay -l output:

Quote:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC660-VD Analog [ALC660-VD Analog]

Subdevice #0: subdevice #0

Subdevices: 1/1
Subdevice #0: subdevice #0

If you have a hdmi device showing up on aplay -l, you just need to run a mixer(alsamixer) find a device that correspond to something digital and unmute it.

Please post yours "aplay -l" in this thread for us to make a comparison.

Finally, I did, I made hdmi sound work on my asus g1s.

Now my aplay -l shows a digital device:

Subdevices: 1/1
Subdevice #0: subdevice #0

I made it work by going to this file "/etc/modprobe.d/alsa-base":

Quote:

sudo gedit /etc/modprobe.d/alsa-base

then I delete all the contents of that file and put this:

Quote:

options snd-hda-intel index=0 model=3stack-660-digout

at "model" you have to put one that is made for your hardware, look here for a complete list of models available.

Then I use alsamixer to unmuted the IEC958.

Now, I have crisp sound on Linux.

M4rc0 · #11 8th October 2008, 07:13 AM

Skeptic, that sounds great!

Can't wait until i get home and try this.

Will post on this thread later.

Thanks a lot for sharing!

skeptic055, I've got an Asus M3N78-EMH HDMI mobo for which aplay - returns
**** List of PLAYBACK Hardware Devices ****

I've tried adding "options snd-hda-intel model=auto" to alsa-base as suggested by the list of models you referenced; still no sound from HDMI. Is my options line correct? Unmuting IE958 on Alsamix makes no difference.

If your aplay -l displays a digital device you don't need to put a line in "/etc/modprobe.d/alsa-base".

What`s your nvidia driver`s version? You need to update your nvidia driver`s to the version 177.80 http://www.nvidia.com/Download/index.aspx?lang=en-us

To unmute IEC958 on alsamixer, you need to select it and type "m".

Oi marco, so brasileiro tambem, mas como esse forum é em inglês, vou escrever em inglês.
Hi marco, I'm Brazilian too, but this forum is in english, so I'll type in english.

I need you to answer a few questions for me be able to help you.

1. Do you have a notebook or a desktop? If you have a desktop:
2. Which mobo do you have?
3. Which video card do you got and what's the driver's version do you have installed?
4. Do you have your pc hook up with your HDTV by an HDMI cable?
5. Is HDMI audio working on Windows?

If the question n. 5 is yes and your aplay -l shows a digital device, then you just need to have nvidia 177.80 installed, run alsamixer and unmute your digital device by pressing the "M" on the keyboard. In my case, is the IEC958.

I'm running 177.78 at the moment but have downloaded 177.80 so will upgrade to that. Thanks for the tip re aplay and alsamixer will try those. BTW I'm running kernel 2.6.24.19
