My system is Intel NUC NUC6i7KYK
I connected the surround amplifier model Onkyo TZ-RZ830 (7.1.2 surround channel, HDMI 2.0)
When I set the 7.1 surround channel, the sound only appears in the front 2 channels, the other channels are silent.
Tone (including subwoofer and no sound)
I use WIN10 1803 and WIN10 1809 new installation test have the same situation
(voice is transmitted as 2 Channel)
But I used another computer to test the new installation of WIN10 1809 (using NVIDIA HDMI)
Set 7.1 surround channels, but all channel sounds can be heard
(voice is transmitted as Multi Channel)
I think this is a question about INTEL HDMI AUDIO DRIVER
I have tested the installation of the following drivers. The same situation (sound delivery is 2 Channel)
WIN10 initial installation driver
In order to find out the problem, I spent 2 days doing different system installations, and doing cross-checking with different NUCs.
Amplifier equipment = Onkyo TX-SR606 / Onkyo TZ-RZ830
PC device = ASRock ION 330 (Nvidia HDMI 1.3) / NUC NUC6i7KYK (Intel Hdmi 2.0)
WINDOWS = WIN10 1803 / WIN10 1809
Test Benchmark HDMI AUDIO 7.1 Transmission Multi Channel Sound
ASRock ION 330 + TX-SR606 + Win 1803 ==> OK
ASRock ION 330 + TX-SR606 + Win 1809 ==> OK
ASRock ION 330 + TZ-RZ830 + Win 1803 ==> OK
ASRock ION 330 + TZ-RZ830 + Win 1809 ==> OK
NUC NUC6i7KYK + TX-SR606 + Win 1803 ==> Fail
NUC NUC6i7KYK + TX-SR606 + Win 1809 ==> Fail
NUC NUC6i7KYK + TZ-RZ830 + Win 1803 ==> Fail
NUC NUC6i7KYK + TZ-RZ830 + Win 1809 ==> Fail
The reason for the failure is that there is only 2 channels of sound (2 Ch) passed to the amplifier, and the remaining 6 channels have no sound at all.
This is very unsatisfactory for the main control computer used in the family living room. I certainly know what caused it.
The answer is that the Intel HDMI Audio Driver is not written. When the user is set to 7.1,
The channel still uses the preset stereo mode to pass
This may be a versatile issue for Intel HDMI Audio, I believe Nvidia or AMD's HDMI
No problem, I plan to sell my NUC NUC6i7K and switch to another HDMI Audio (which costs me $700 more)
Please switch to 4 channels or more. If you switch stereo, you will still hear all the sounds (because WINDOWS will automatically convert)
Protplayer, Please select passthrough mode
You have to hear the details of the sound that the ball rolls to the back, which is completely inaudible in Intel HDMI Audio.
You have to hear all the corresponding speakers, but only the first 2 speakers, the other sounds are gone.
Can anyone help forward this article to the Intel driver opener, changing the 2 channel to the multi-channel setting?
It should take some time, this is a problem with Intel HDMI Audio, but for a home theater PC,
This is a very important feature, thank you very much for your assistance.
