Solved: Re: HDMI Audio loses layout on Haswell and Silent Stream Bug - Page 2

osetn · ‎10-21-2013

First Problem i have: (nothing found in Web about this isue)

On Win7 Haswell HDMI audio loses layout (example - center outputs on Rear left and so on). this happens especially after refresh rate change. Only Restarting the PC will help (tried deactivating hdmi audio, replug hdmi, ...).

I have testet this on serveral Mainboards and Processors.

The Problem excists randomly, and is difficult to reproduce.

Second problem:

the well known Silent Stream Bug (on Haswell, Sandy, Ivy). This is a no-go for mediacenter PC (ATI has fixed this isue). When will this be fixed on Intel?

When No Sound played in Windows, a Connected HDMI AMP switches to No Signal.

HDMI should permanent send Silent Audio, otherwise HDMI receivers cannot sync to signal (they dont know if there is 5.1 or 2 channel PCM audio).

Is intel aware of these issues and working on it?

regards, onur

I am also having the HDMI channel layout issue with Intel HD Graphics / Display Audio. I have a Dell Inspiron 3647 small desktop with a Haswell Pentium hooked up to my Preamp (Emotiva UMC-200) via an HDMI cable. I can reproduce the issue using J River Media Center. I have the audio output set to 192 KHz/24-bit 5.1 PCM audio when watching movies (@ 23.98 fps) using a WASAPI interface for audio. If I repeatedly switch between watching different movies and skip around within the movies, eventually the channel mapping will become wrong and stay that way until the computer is rebooted. I can also just leave the computer on for a while and many times I will try to play a movie and the channel mapping issue will occur.

Bitstreaming audio (Dolby Digital / DTS-HD) directly to the Preamp will many times just stop working too until the computer is rebooted.

In order to eliminate J River Media Center as the source of the problem, I can close it and open the Windows sound test application which will still play audio out of the wrong channels. In order to eliminate the Pre Amp as the source of the problem, I unplugged the HDMI cable from the computer and then connected my TV to the computer with another HDMI cable. While the TV only supports a stereo input, the left/right channels will be swapped. So once the issue occurs with 5.1 audio, it will carry over to 2 channel audio. Rebooting the system is the only way to correct the issue.

I am currently using the Intel HD Graphics / Display Audio drivers provided on the Dell website, but if I use the latest version from the Intel website, the issue seems to get worse. This issue cannot be fixed by powering on/off any device connected to the PC or replugging in the HDMI cable.

Unfortunately for me it seems to be getting more and more common. I have to reboot about once per week when the channels get messed up. I have updated to the latest beta drivers as well but it seems that Intel isn't even acknowledging that there is an issue.

I am experiencing the same issues on an Intel Nuc w/ i3 4010U, but the beta drivers you posted what install for that processor. Any ideas how I can fix this issue on my NUC? I am running Windows 7 64bit...

Thanks

I have the same issues with my Intel NUC NUC6i7KYK(Scull Canyon) running Windows 10 Pro.

And as I'm using it as a mediacenter it's a really annoying bug that needs to be fixed immediately!

I'm running all the latest firmwares and drivers.

It's really annoying that I have to use optical audio output when I could be using HDMI with return channel so I just have to have one remote for the entire setup instead of one for TV and one for receiver.
