Optimus, HDMI, full-time 5.1 audio -- How?

[MFili11]

Win10-1803.

I have a 5.1 HDMI audio extractor connected to an Optimus system. The integrated GPU is Intel(R) HD Graphics 530.

Since the TV is 2.0 audio, that's all I'm getting. I want 5.1 audio and I want it 100% of the time, no matter what's plugged in, no matter whether nothing's plugged in, no matter whether whatever is plugged in is ON or OFF.

Any ideas how I can achieve that?

Regards,

Mark.

Hello MFili11,

Thank you for posting on the Intel® communities and for the details provided.

In order for us to understand better the configuration you are trying to achieve, could you please confirm the following information?

1- Please elaborate more on how exactly you are connecting all the devices? How are the devices connected to one another? cables types, etc.

2- Brand and model of the 5.1 HDMI audio extractor, TV and "Optimus system". You may also provide some links as a reference.

3- Please provide more details on what you are trying to achieve. For instance, are you trying to output the audio signal from the system and play it on the sound device from the Audio extractor?

Hi Andrew,

I'm conducting some tests that require HDMI audio to be on continuously instead of loading & unloading.

Hello MFili11,

Thank you for your response.

However, we would need to understand better how you are connecting the devices and more information like brand and models (links as a reference, etc.)

1- Please describe in detail how the devices are connected to one another and provide details about video outputs, cables, adapters (if any) in use.

2- Brand and model of the 5.1 HDMI audio extractor, TV and "Optimus system". You may also provide some links as a reference.

Hi Andrew,

I appreciate that you want to solve a problem here. I have many problems including channels not driven (2.0 versus 5.1), Windows crashing when HDMI is unplugged, symptoms that change depending whether the HDMI is directly plugged in (thereby connected to the Intel 530) or plugged into the DisplayPort (thereby connected to the NVIDIA 980M). I'm conducting tests to narrow down the issue but those tests require the HDMI be loaded and continuously driven.

You ask for details, so of course I will provide them.

The 5.1 HDMI Audio Extractor is externally powered, and it connects to audio amplifiers via 6 RCA jacks.

I have more information.

With HDMI connected, when I shut off power to the HDMI Audio Extractor, Windows throws an exception.

Here is the Event Viewer records of Windows crashes that I presume were caused by HdAudio.sys when power to the HDMI Audio Extractor was disconnected. A fresh dump can be created whenever you'd like; all I have to do is disconnect HDMI. Note that the latest crash, not summarized below, was today when I disconnected the power to the HDMI endpoint. On the blue screen, as Windows thought it was sending a report to Microsoft, the screen said "PAGE FAULT IN NONPAGED AREA" but it didn't cite a cause. I presume that that crash overwrote C:\WINDOWS\MEMORY.DMP, but like I wrote above, I can reproduce the HdAudio.sys crash on demand.

Hello MFili11,

Thank you for all the details provided and for your patience in this matter.

After investigating this situation, we would like to inform you that the driver will read the EDID (Extended Display Identification Data) from the end-point device and if it is 5.1 capable it will allow Windows configuration to be set as 5.1.

We tested this with the latest driver 26.20.100.7463 and connecting an Intel® NUC to an Onkyo 5.1 Receiver (HT-R395)*. Please find a screenshot attached.

At this point, we kindly recommend you to address this question to the manufacturer of the HDMI audio extractor device and contact their support team for more accurate assistance.

Regards,

Andrew G.
