Sound through hdmi with nvidia GTX460

[niiklas]

Im trying to get my nvidia gtx 460 to send the audio through hdmi. Got it working on my w7 install but not with ubuntu.

I tried to install & compile the latest alsa driver without success, this is how my alsa mixer looks like:


Aplay -l shows this:

Anyone that has sound through hdmi with a discrete nvidia graphics card? How did you do it?

I typed

alsamixer

in Terminal and scrolled over to "S/PDIF" and pressed m. This un-muted my HDMI audio and caused jolly good times to commence. I hope this solves your problem

Couldnt find any S/PDIF in my nvidia tab, but unmuted on the other soundcards without any luck...


No controls for the nvidia soundcard~

anyone?

I do have exactly the same problem.

I do get the sound from HDMI with Windows 7 64 but no sound with Ubuntu 10.04 64.
I tried alsamixer on Terminal and S/PDIF outputs are un-muted. But still no sound. Do I have to change anything in BIOS settings. Such as; HDMI settings from HDMI output to S/PDIF? If I do, do I have to change any cable config on motherboard?

My System;
Ubuntu 10.04 64
Asus P5Q-EM Motherboard
Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz
8002 MB Memory
Nvidia GTX 460

Same error as you guys. I should be able to select HDMI as a source from System=>Preferences=>Sound

Maybe this will be fixed in later drivers? Is this a problem with Ubuntu or nvidia?

I thought *maybe* BIOS but I'm pretty sure this is a software problem.

Groucho, could you tell us what package versions you have installed (alsa-base, alsa-utils, linux-headers-alsa-driver, linux-alsa-driver-modules)? Did you compile anything yourself? Clearly you're able to access a bunch of controls that the rest of us can't find using the same hardware, which makes me think that there's a package or two the rest of us are missing.

Thanks,
Tavis

are all nvidia GTX 460 the same? there's like 20 different boards for those.

Mine is a EVGA, but I have seen several threads with the exact same problem for the exact same card. It seems to stretch across all brands. I agree with the earlier poster that it may be a software issue, as true video card only HDMI sound is still pretty young.

I would also like to know Groucho's setup/card brand.

By the way, there seem to be some kernel issues involved; it appears that a custom kernel is required. See this thread on the Nvidia linux driver forums:

Also, this Ubuntu bug report and the discussion:

https://bugs.launchpad.net/ubuntu/+s...ux/+bug/611810

It's not clear to me which compilations of ALSA or kernel backports (if any) do contain the right patches.
