AMD HDMI Audio Problems

post #1 of 8
Thread Starter 
Hi All

I'm running my second rig in sig as at HTPC in the lounge.

In the lounge I had a DVI to HDMI adapter (which came with my card) connected to a HDMI cable to the lounge TV. This setup is awesome and AMD HDMI audio (something I never knew existed lol) works fine so both video and audio go through the HDMI cable into the TV.

Last night I finally got round to moving my old flat screen into the bedroom. I have run a HDMI cable under the floor from the HTPC in the lounge into the TV in the bedroom.

The problem is that AMD HDMI audio does not get sent down the second DVI port in my graphics card (which is going to the second TV in the bedroom). Video works fine, but no sound.

I found out that AMD HDMI audio will not send two signals out each port so I'm in a bit of a jam.

I'm just wondering, will using something like this: http://www.computerstore.co.nz/AT-HDMI-TO-HDMIX2.aspx

Allow me to connect both my lounge TV and my bedroom TV to the same port on my graphics card, and both TV's getting a duplicate video and audio signals? (Which is what I want).

Thanks in advance.

If there is no encryption then the video signal can be duplicated. But there is encryption and only one device is going to negotiate the signal. The other device will not pick up a picture. HDMI audio and video signals are encrypted. I don't know where you are located but this is what you need:

Why would there be encryption?

HDMI specification says it. If there is no encryption going across, just make sure you don't ever play a movie from dvd or bluray. If you use this splitter, and do play a encrypted source video/audio file, you will get a black screen or message on one of the monitors. If it was a dvi signal you could split it without issue. But again you will not have audio. The dvi jacks on the ati cards do output audio but you have to use a dvi to hdmi adapter specifically made for ati cards.

Um ok, not sure i get this stuff lol

At the moment I have a DVI to HDMI adapter that came with the card, this sends video and audio (via HDMI cable) to my TV which works fine (also plays DVDs and BluRays fine).

So if I got a simple HDMI splitter (like the one I linked in the OP) and plug that into the DVI to HDMI adapter that is currently connected to my graphics card DVI port. And then plug two separate HDMI cables into the splitter, each going to a separate TV. Would that work?

Or am I still confused haha.

Pardon me I talk in geek too much. To put it simple the splitter you choose in the first post is strictly for video. You won't get audio.

One last thing, depending on your video card you should be able to do two hdmi connections. Sorry I totally missed that. You have one hdmi jack built in and another where you can get a ati dvi to hdmi dongle or a displayport to hdmi dongle. So my question is what brand did you put into your htpc?
