No video when using HDMI audio

I plugged in the hdmi cable from my gtx 580 to the receiver. I have my CRT plugged into the DVI closest to the HDMI port. When windows boots up all I get is a cursor no picture.

Then I tried the second DVI and I got no picture and no mouse cursor at boot up. The card works fine before it gets to the window prompt.

Under my playback devices for sound. I have 4 hdmi audio devices not enabled. Each one has a picture of a LCD next to it. Also one of them has the denon receiver not enabled.

I shutdown unplug the HDMI cable and I can get into windows again.

I'm new to hdmi audio. My guess is the drivers are trying to send the picture over the HDMI and not just the audio. Anyway what do I need to do?

If I can't get this to work I'll have to return the denon 591 since it doesn't have analog inputs for 4.1 sound.

Well I figured out what was going on. The nvidia drivers are treating the HDMI connection to the receiver as a second display. So some stuff is appearing off screen.

I got past the login prompt. Then saw a blue desktop. I knew i was looking at part of the desktop. I was able to get into the display properties. And switch it from denon to VGA.

I don't know why I'm having so many issues. Hopefully people that set up HTPCs know what I can do to fix this.

Now all the HDMI audio drivers in the play back devices say unplugged. Do I have to get a 3rd party hdmi audio driver?

Here is a list of all the hdmi audio drivers. I find it odd that it lists 4 of them when I only have the one on the 580.

I'm a little confused by the posts, but it sounds like you are using the HDMI cable for just audio. HDMI is for audio AND video. You have 2 video connections currently, which means the computer thinks is has dual displays. All you need is an HDMI from the computer to the receiver, and another from the receiver to your display. I could be wrong, there might be a workaround or I could have misinterpreted your problem, but anything other than this will probably not work due to HDCP protection.
 
Yeah I can't do that cause my display is a CRT which takes an analog RGB single. That comes from the DVI out on the videocard using a DVI to analog CRT cable.

So if my receiver ever breaks I'm screwed cause none of the new receivers have analog inputs and there is no way for me to use the sound chip on the videocard for sound only.

If I was to use an HDMI sound card would that work or would the video card think the HDMI on the sound card is for video and try to use that? But the whole idea was to stop needing a sound card for good sound.

You're going to have to use S/PDIF out. Does your motherboard have a coaxial or optical S/PDIF output?
 
Sound card has optical out. But if I have to go that route I may as well just return the receiver. Sending 5.1 channel sound over is compressed audio which may sound worse than my current analog setup.
 
Ill be honest... unless you have a properly setup space with all the necessary acoustic treatments, you probably aren't going to notice the difference. You have to consider all the links in the chain of proper quality audio. I've found over the years that its the room that makes the biggest difference to audio.

I've complete shit speakers in properly setup spaces and had them sound great.

In a normal living room, the difference between Dolby Digital and TrueHD will not be apparent.
 
Well gave DDL another shot and I'm limited to stereo. Someone said in the control panel but I see no way to switch to 4 speakers. I just have the audio driver installed since I don't want all the bloat with the drivers.

Is there a speaker app I have to install to switch it to 4 speaker or so?
 
I got DDL working on my old receiver. My old receiver sucks I have to keep setting it to right mode for DD otherwise it sends back to the front.

Think I'll try it on the new one.

Thanks

Again, HDMI is for audio and video, end of story. If your monitor doesn't support HDMI, you will need to use a optical cable from your sound card to your receiver in addition to your normal video cable. You should be able to set your sound card to just pass the audio signal to your receiver. In this situation you shouldn't need to configure anything in the control panel since the computer is just passing the audio signal on. The receiver would be what you need to make adjustments on.


I would fully install the drivers as well. I don't understand how drivers could be "bloated".

Also, I'm not sure why you think the optical signal is compressed. I'm not an audiophile so it very well could be doing something that slightly degrades the quality, but it is probably not noticeable. It was mentioned earlier, there are 15 other things involved that can degrade audio quality way more than this. It would be like upgrading your side view mirrors to get better gas mileage. It will have an effect, but there are bigger things to worry about.;)

Honestly, if I were you, I would be upgrading that monitor. Using HDMI start to finish might solve your problem the easiest.
 
What is your sound card? There is no "Dolby Digital Live" On receivers if you see it it is just some sound processing stuff.

DDL is a system that converts 5.1 of internal computer PCM data into a SPDIF Dolby Digital out that is the same to the receiver as say from a DVD. It is just done on the fly with extremely little latency.

DDL is for gaming. In a normal situation you want to enable DDL before going into games not before or after so that #1 You system's Dolby Pro Logic works on Internet video or other 2 channel sources. #2 A normal DVD play can override the PCM and send good multichannel DD or DTS down.

Edit: BTW atleast on my DDL system to get DDL working I have to make sure that windows sound is set to speakers NOT the digital out. Digital out is handled by the card in hardware windows wont send 5.1 audio to what it thinks is a SPDIF output. Set settings correctly in the settings of your device drivers (I use Turtle Beach)
 
I returned the 591. It was useless to use since I couldn't use HDMI for audio only.
Using my denon 2700 avr 11 year old receiver again.
I tried DDL sounded fine but was limited to 48k. So went back to analog at 96k.
Also if I turned off DDL and turn it back on my receiver would put everything thru the front speakers and I would have to switch to a different mode. So to avoid the hassle I just went back to analog. Only time I have to manual change anything on the receiver is for DD movies. I'm sure new receivers don't have this problem. But wasn't worth the cost to fix a minor problem.

Creative comes with a lot of extra apps you don't need. I been using just the drivers and been able to do everything thru them with no issues.

So now looking for some speakers to replace my cambridge soundworks ensemble 4 that use a shoebox type woofer for something that doesn't. Figure my speaker system could probably use an improvement.

All my hardware is listed in system specs.

Yeah I know DDL is software driven and sent to the receiver :)
