Another HDMI audio/video sync issue - Win Media Center & x.1 configs

[kdeho2]

All:

Reporting this as a clue to help track down the driver issues others are seeing that are making HTPC use nearly impossible. I'm building a new NUC 54250WYK with HD Graphics 5000 (replacing an older i3 NUC so my existing AVR/Projector should be deemed working fine).

I've observed three issues

1. In Windows Media Center trying to tune to a HD Homerun Prime channel. Any Speaker configuration other than 2.0 causes WMC to fail with a video error - and I get a curious 1 second audio loop for the few seconds it takes wmc to get the error. I've tried 7.1 and the 5.1s with the same result. WMC works rock solid at 2.0.

2. In Powerdvd 13 I am trying to use 'non-decoded high definition audio' to bitstream a high def audio disc. This results in complete instability in both the player (hangs) and also in the amplifier - my amp will stop accepting IR commands and I have monitored the amp 'hunting' for the signal format on a status page (denon 4311ci). The workaround is to not use this particular audio track - I'm really looking forward to a fix! If you need any additional info please send a message.

3. Channel Mapping in all configurations to my Denon is wrong (stereo, 3.1,5.1,7.1...) - several have no center channel output, lfe is routed to left rear and even stereo has left and right swapped. Workaround is to reboot and ensure the amp is on after windows comes up - seems to improve this.

This is a new build of 8.1 I just started yesterday so there's not a lot of junk from the past in it.

I've also tested my old NUC - it does not have any of these problems in the same situation.

Hi nm_nuc_user,

I appreciate the information you have provided.

I would like to get some more information so we can report the problems you found. Can you please post your dxdiag report here and the graphics report? Please make sure all drivers (BIOS, Graphics) are up to date before getting the reports.

Also if you can provide any image will be very useful.

Here is the dxdiag file from this NUC and I also demonstrated the first problem - it is very easy to reproduce. The other two problems I classify as intermittent - I'll work on getting them captured as well. Here is the video of the audio loop with wmc.

nm_nuc_user,

Thanks for the information. I will make sure all this is forwarded to the corresponding department for future considerations.

Hello

Just want to say that I have the exact same problem

The funny thing is that we are not using the same version of windows but it seems to me that we

both have a Denon amplifier/receiver.

I was suddenly having this issue my windows 7 64 Mediecenter computer and I decided to format and reinstall it all again.

But sadly, I was still having the same problem.

If I don't watch HD channels with surround sound then there is no problems.

My setup is like this:

Home build computer with:

Motherboard Asus P8Z68 Deluxe – This also has some build in Intel graphic accelerator witch I am

thinking cud be making the problem.

Graphic card NVidia GeForce GTX 660 Ti connected to my Denon amplifier/receiver with HDMI

Denon Receiver / Amplifier connected to my (Sony Bravia 55 TV) with HDMI

Other issues that might also have some influence: device manager is showing High Definition Audio Device can't start in device manager.

Hope that someone can

help
