Beachman, this behavior could be related to a compatibility between the NUC and the USB sound card. We haven’t tested this product combination.
I would recommend you to run the latest BIOS available for the NUC and check with the product manufacture if there is any firmware update available for the sound card.
Same problem here. I have a NUC D34010WYK and Displayport to HDMI in my Philips TV. XBMC works fine with Dolby Digital but the Netflix app in W8.1 get mi 1-2 FPS with Dolby Digital Plus. This is the Video of my trouble: Intel NUCE 5.1 sound problem with Netflix - YouTube
And a picture of the solution in Windows 8 Swedish OS: http://s26.postimg.org/6nwlskqmh/settings_sound_windows.png
Thanks for the information Stormense.
Would you please let me know which is the current graphic driver installed on your NUC?
The latest on our website. All drivers include BIOS.
Google translation from Swedish
Did, however, it was a bit tricky to download the drivers from your page. You select Windows 8.1 64-bit OS but get that first choice Windows 7 32-bit. Do not understand why to choose OS when it looks to settle. I made it wrong first
Would you please uninstall the graphics driver you installed and try with the following version? This file comes directly from the Graphics download page. This driver is valid for Windows* 7/8/8.1 32-bit and 64-bit
There is also a BETA driver that we are testing, if you want you can try it and then you can let me know your findings.This driver is valid for Windows* 7/8/8.1 32-bit and 64-bit
About the beta driver
No, the same problem that you have to set the audio settings if you want to have 5.1 sound in Netflix app to get rid of the image will hack. Think it's a huge mistake by Intel to not have optical audio output on their NUC. Madly decision by someone because I think just lovers of good film and good sound bought NUC.
Okay, you can connect the HDMI directly to your TV, but only gets 2.0 audio with DTS tec. By The receiver you will receive Channel Direct with my settings and NUCE is coding sound instead of your expensive receiver.
Again, a terrible decision by Intel to not have optical or a functioning HDMI.
NUC D34010WYK - Philips TV - Onkoy Resiver with HDMI
The same sound problem with latest drivers. Uninstalled Beta driver quickly because HDMI handshake with TV or Reciver broke down.
(I run Dispay port HDMI adapet 1.4 for I havent any mini HDMI).
Can Netflix Dolby digital plus problem may be that the NUC i3 is a too weak computer?
I have customer reporting that Netflix is running fine with DD 5.1 sound after the downgraded to Windows 8.0.
Could you please remove our graphics driver complete and try using microsoft’s? Let me know if Neflix works OK.
Are you using a wireless connection? If you do, could you try using regular wired connection?
If I remove Intel graphics driver complete and try using microsoft’s I get no Picture from Displayport to HDMI. Im using Lan cables. The Netflix-app works perfect with my computer with Ivy Bridge I7-K Nvidia graphic GTX680 and sound card Creative Z.
The OS is Windows 8.1 on booth.
After much testing regarding this issue, we found a very simple workaround (at least with the Denon receiver tested here). In Control Panel > Sound, open the properties for the receiver on the Playback tab. Go to the Advanced tab and disable both of the Exclusive Mode options you see there.
Now check how the Dolby Digital 5.1 behaves. On our lab system, it immediately solved the problem. I'd like to get confirmation from others before I add this to our troubleshooting documentation on the support website.
Unchecking exclusive mode makes Netflix app play 5.1 audio in stereo, it's not playing in dd+ as the AVR shows PCM instead of Dolby Digital+ and yes I've checked that the 5.1 is selected in Netflix
I only started having this problem when I installed the graphics driver from intel rather than the one that came via Windows update. The problem with using the MS driver is that it doesn't list all supported formats of my receiver such as TrueHD etc whereas the intel driver does
Note, I'm running a D54250WYK with HDMI to a Yamaha AVR. Using latest bios 26 and latest intel graphics driver 3621
@lhill @syvia_intel I can't believe this bug has been around for more than six months with no resolution in sight. It simply makes it impossible for the NUC (or any other machine with an Haswell iGPU) to be used as a primary HTPC.
As a background, I was the reviewer on AnandTech who wrote about this issue in my review of the Intel D54250WYK NUC kit [ AnandTech | Intel's Haswell NUC: D54250WYK UCFF PC Review ]. Since then, I have evaluated multiple mini-PCs. Every single unit that I have evaluated (Zotac's ZBOX-EI750, Gigabyte BRIX Pro, Gigabyte BRIX etc.) fails in the Netflix / DD+ 5.1 bitstreaming issue with the Win 8.1 Netflix Metro app if the Intel audio driver is used. I believe this issue is not restricted to the NUC alone. Using the Microsoft HD Audio driver enables proper DD+ bitstreaming to the AVR, but we lose out on HD audio bitstreaming (TrueHD / DTS-HD) support from other applications. So, the bug is definitely in the Intel Display Audio driver. Tried messing around with the exclusive settings in the Properties panel, but no effect. (Interestingly, XBMC also has a similar issue that is easily resolved by altering the Audio properties to use DirectSound / take exclusive access of the sound device).
My A/V test setup involves a Pioneer VSX-32 receiver connected to a Sony KDL46EX720. I am in the SF Bay Area in case anyone at Intel wants some help in replicating the issue. I most recently tested this yesterday in the BRIX Pro with the drivers released on May 21st (v.3621).
Google translate again, I'm sorry:
I bought a VIA USB sound-card that thread creator. Was better with that one. Now it is really sound out of XBMC but Netflix problem is still there. As he writes above: Intel is unable to resolve this. Personally, I believe it is a hardware problem. There are similar problems with other new products from Intel.
Saying now that I said to former BIG Nokia before they went the way I predicted:
- Listen to customers and sharpen . It's not them they are wrong, it is you.
