Will there ever be HDMI Audio support?

[JackDanielz]

Its a pretty simple question, I've read in the NVidia forums that there is no HDMI Audio support in the current drivers which would explain why I can hook up my plasma no problem and video is great but I get no sound.


My question is whether they are working on it or is this just a pipe dream for me?

[JackDanielz]

judging by the lack of replies to my question, the answer is probably not.

In order to attempt to help you please provide more details...

- What soundcard do you have ?
- what OS do you run
also what output do you get from these commands (ran as root)

I'm sorry I'm not sure that you understand. I'm pretty sure my soudcard has noting to do with the HDMI on my video card, but I'll try to answer your questions anyway.

lshal was so long I could not fit it...

There are a few NV cards available which have an SPDIF
input connector (to loop spdif signals from sound-out to the HDMI connector). Other than that there's no way
I can think of to get audio onto the HDMI cable (well, you could open the connector on one end and solder audio cables onto it )

Thanks for the input and yes im aware of the NV cards with spdif connectors but this is a laptop so i think thats a no go.

What about all-onboard solutions where the motherboard itself has HDMI out. I believe the hardware is capable of this in another operating system.

In my case, it is an onboard ATI instead of an add-on nvidia. Is this something that is possible, or is this a fglrx issue?

EDIT: Didn't see this was a laptop, so it is not an addon card. Probably a similar situation then.

ATI hardware has an integrated APU for sound support for all of their R600/700 ASICs. These should be supported by ALSA.

Yea I was gonna say I thought this was an Nvidia specific problem within the driver... AFAIK ATI Cards shouldn't have this problem, thats the reason I originally asked if there would be support assuming that if anyone had any inside information on Nvidia's driver plans they would chime in, but I guess not.

Sometimes you can add a SPDIF connector to your gfx card.
