HDMI sound lost

BAlve2 — Mon, 17 Oct 2016 01:12:09 GMT

I have two windows 7 PCs with i3-6100 providing graphics and sound through HDMI. Both of them sporadically have the HDMI sound go away. Typically, the playback audio devices no longer shows an entry for "Intel(R) Dispay Audio" and has a red X. Typically I can fix it by uninstalling the "Intel(R) Display Audio" driver and then scan for hardware changes to reinstall it. Occasionally it is more complicated, but if this could be fixed it would be a huge improvement. One of the PCs is an HTPC where it is very user un-friendly to have to pull out a mouse and walk through the steps to reinstall to get sound working, particularly for family members who just want to watch recorded TV.

Currently I am running the 4463 driver. I tried the 4501 driver but it seemed markedly worse with respect to hitting this problem. Of course I could have just been unlucky since it is sporadic. However we still hit it almost every day at least once. I attached the SSU for the HTPC taken while I had the "red X". The HTPC is connected to an Insignia 37 inch TV via HDMI. I have also hit the problem on a desktop PC connected to a HP 2310m display. Any ideas on how to avoid this problem or track it down so it can be fixed?

Have you tried changing the HDMI cable?

I understand that using low-quality cables may cause this type of behaviour.

Please let me know once you test HDMI cables.

I can try different HDMI cables, but note that the problem is already occurring on two different systems for me. Each has their own motherboard (not the same), both have i3-6100 processors, each has their own HDMI cable, and each has a different monitor (one a TV, the other an HP monitor). Also, both systems were upgraded from AMD AM3 based systems. Neither of those systems had any trouble with the same HDMI cables and monitors.

Please try different cables and if possible load the following graphics drivers:

I have seen the same issue with the last 2 beta drivers. It is NOT my cable because immediately after uninstalling the beta update and reinstalling the latest non-beta driver, the Intel Audio driver reinstalls and the sound works again. This can be repeated endlessly. My monitor is a Dell U3515W.

I will check this issue internally and update this thread with my findings.

I swapped the cable with a different system and have the same problem on the computer with the Insignia TV display. So, changing the cable did not affect the problem. I have not changed the driver yet; didn't want to change more than one thing at a time.

Were you able install new graphics drivers?

Yes, I tried the 4539 experimental driver. I noticed that the included Display Audio driver version is 3197, the same as with 4464. It only took one sleep-resume cycle to get the Red X. Maybe if they actually changed the Display Audio driver there would be some real hope.

I had the same problem, the last drivers are broken. I had to roll back to 4360.

Now I'm using driver 4360 and it works well.

I couldn't find that driver version (4360) on the Intel site, but I did try 4424. It has the audio driver version 3196 (i.e. not 3197). It still fails in the same way.

I downloaded version 4360 from the official MSI site some weeks ago.

Now I'm using version 21.20.16.4534 with Intel Display Audio version 10.22.0.37. I don't have this problem anymore. I installed them through Windows Device Manager

I have now tried the following drivers and had them fail:

15.40.xx.4539

15.40.28.4501

15.40.25.4464

15.40.22.4424

I am now trying 15.40.10.4300. It also happens to be the driver on the Asrock website for my motherboard, but is very old. I'm not sure if your 21.20.16.4534 applies to my 6th gen Skylake cpu graphics. I don't see anything like it on Intel's list of drivers for my hardware.

Re: HDMI sound lost

I have checked the *.cab file (4534 ) and it does show SKL or Skylake support for Win 7-8-8.1-10

Yes, I have Skylake i5-6600 and it works well.

I'd be willing to try it if I could get it. I don't see 4534 available on the Intel driver download site, and google doesn't find any Intel source for it.

Here is the download page I get to for 6th gen processor graphics drivers for Windows 7 64 bit: https://downloadcenter.intel.com/product/97502/Graphics-for-6th-Generation-Intel-Processors Downloads for Graphics for 6th Generation Intel® Processors

At this point I have tried just about every non-Beta driver listed there, as well as the latest greatest Beta.

4534 is Microsoft version, you have to download it through Device Manager as I said.

Just install an older version and update it.

Ok, got 4534 from windows update and it failed instantly. This was in a worse way, where the Intel Display Audio device is not even listed under the sound controllers. This happens sometimes with the other drivers, so it might be bad luck. But it is a pain, because the only way to fix it is to reboot and hope or to reinstall a different driver.

What OS do you use? Windows 7? What is this, 2008?

Re: HDMI sound lost

BAlve2 — Sat, 12 Nov 2016 20:20:35 GMT

Windows 7, 64 bit, fully updated. Google does find the Red X problem with Intel Graphics HDMI audio going back quite a ways.
