no audio over HDMI

[feh]

This problem has been solved. I don't have the version of the nvidia driver that took care of it handy - if you need to know, please contact me and I'll get back to you.

------------------------------------------------------------------

Hi folks.

I installed RC 7100 on my new HTPC build a couple days ago. Everything went pretty smoothly, except for audio.

The machine is connected to an HDTV via HDMI, and I've got no audio at all. The stock MS drivers that were used out of the box didn't provide sound, and the latest Nvidia drivers didn't help either.

It's not a configuration issue with either the TV or the machine's BIOS, as I previously had linux installed on the same machine, and I had audio over HDMI.

Any thoughts or troubleshooting tips? Thanks!

feh, welcome to the forums.

Assuming that the option is there, did you set HDMI Out as the default audio device in the Windows playback properties?

Yes, I set HDMI as the default device.

No promises as you have to use the Vista driver, but do you have the latest Via audio driver installed (VIA VT1708B is the chipset)?

No, I have not installed them. I did install the Nvidia HDMI drivers.

Which begs a question...this is the first time I've bought/used a multimedia/htpc motherboard. There is onboard audio for 7.1 sound; is the same audio chipset used for both the "standard" audio output jacks as what gets pushed out the HDMI? Is it a completely different chipset?

Knowing what hardware is used for HDMI audio would instruct me on what drivers to search for.

First I wanted to say Hi and welcome to SF. I also wanted to say thank you for filling in your system specs. It makes troubleshooting a whole lot easier. I fyou did a clean install when you installed win 7 chances are its a driver issue. Dont know if you hae 64 or 32 bit but why dont you try a search here in SF for your model graphics card and see if there is a thread that deals with iy. It seems thre have been a number of hdmi audio and video problems. the other option is to try upgrading to a newer win 7 build. M$ may have addressed your specific driver issue in a later build

Hope this helps and I will keep an eye on this thread in case you need more help

Unless Nvidia has done something totally different to how HDMI audio works with the onboard video over an actual video card (requires the use of a SPDIF cable from the sound card to the video card, which I can see being built-in to the board for the anboard video), then the onboard audio needs to be enabled and the drivers installed to work properly.

Ok, thanks for the info. I'll check out the VIA drivers tonight.

For what it's worth - the nvidia site did have downloads for HDMI audio for this board. Perhaps they were just repackaged VIA drivers?

Thanks for the welcome.

FWIW - I'm using the 64 bit version of the OS and drivers.

FYI - I installed the VIA driver, which made no difference at all; still no audio over HDMI.

I do have audio through the analog pin connector (line out), but that does me no good when connected to my HDTV.

feh something for you to check. I went looking for manuals from other boards that use the same GF8200 chipset as yours and have an HDMI port. Anyway came across one and it has a setting in the bios to enable the HDMI audio, and it is disabled by default. Worth having a look in your bios under "Advanced Chipset Setup" or possibly 'Integrated Peripherals" and see if yours has a similar setting.

I've played with every option in the BIOS. The only setting related to sound is the ability to enable/disable what they refer to as the internal (nvidia, over HDMI) and external (VIA, using the 8 pin-style connectors) sound systems. None of the available settings work.

Plus, HDMI audio worked fine when I was using linux, so I'm 99% sure this is either a driver or OS issue.

Thanks, though.

feh,
Did you get audio over HDMI working? I have been trying to find a solution and coming up blank.

I did find the link below, but it didn't help.

Yes, I did get it working. I ended up getting tech support from nvidia - they had me use an older version of the video/audio drivers, and that enabled HDMI audio.

Hi Feh,

It would be a good thing to edit your first post,
and write that you have found a solution.

And tell people which driver solved your problem.

182 seems to do the trick

I got it Working too

I feel stupid as after posting my response to feh I found my problem.

It basically boiled down to me wanting to go through my receiver for audio. Problem is my receiver does "pass through" HDMI. This means it sends audio and video to the same source and only to that source when using HDMI. So I had my computer plugged into DVD and was sending my video out to my TV. Well my receiver won't play audio out the speakers connected to it in this scenario without a separate cable for audio when using HDMI as it sends the audio signal to the TV as well.

So unfortunately, until I figure something else out, I am running audio through my TV. I would just use a separate digital cable for audio, but my digital audio ports are filled at the moment. But at least I know what was causing my issue.
