Arc A770 Audio Issue

[Pragmatist]

Hello,

I have an Arc A770 that is working well on my system except for one persistent audio issue.  I technically have a workaround but the issue is clearly a bug.  I am on Win10, Ryzen3700X, MSI B450M motherboard, 4314 drivers for ARC.

My audio is using HDMI from the Arc to my Samsung Q90B television.  My motherboard's onboard audio is disabled to prevent conflict.  The issue is that every time I start my system and log into Windows, my audio is always disabled.  The little speaker icon to change audio/volume settings in the lower right corner is crossed with a red line and when I click on it, Windows goes into diagnostic mode.  But it fails to identify the problem if I use it.

The solution that works to fix it is to go into device manager, go to "sound, video and game controllers" then disable and re-enable "HD Audio Driver for Display Audio."  This consistently corrects the issue and audio then works.  For some reason, when it is re-enabled, device manager then shows 2 "HD Audio Driver for Display Audio" instead of 1.

A fix for this issue would be appreciated.

Thank you.

Hello, thanks for the response.

I've had this issue right at the offset as soon as I installed the card.  The card was installed on top of a fresh Windows 10 installation, so there's definitely no remnants from past drivers.  Resizable bar is enabled.

The 2 reports have been attached.

I tried my second port and no luck.  Also did a clean install of those beta drivers and the issue persists.

first, why do you even consider disabeling the onboard audio?

for my understanding the GPUs never have there own audio chips and rely on the onboard or separated audio HW.

they just redirect the audio to the hdmi port at the end.

so i dont think it will ever work if you dont reenable your audio HW.

Hello Pragmatist,

We were working on the investigation, and we were unable to replicate the issue, please follow the steps below a let us know the results:

1. Test it with a different monitor or TV.
2. Test it with different cables.
3. Uninstall the current driver using Display Driver Uninstaller. Check How to Use the Display Driver Uninstaller (DDU) to Uninstall an Intel® Graphics Driver for instructions.
4. Update graphics driver to version 31.0.101.4314. For installation steps, How to Install an Intel® Graphics Driver in Windows® 10 & Windows 11 (Method 2).

Thanks for the suggestions.  I won't be trying it on a different monitor, simply due to the fact that I don't have one.  I've tried different cables and no luck.

I also tried Neo-Freeman's suggestion and it didn't change anything as well.  When I re-enabled my motherboard audio, Windows recognized it as spdif, but obviously no sound was provided since I didn't have my motherboard's audio options plugged into my TV.  The ARC's audio option was not even recognised in the audio options, and the same step of disabling it then re-enabling it in device manager got it working again.

I'll wait and see if future driver versions fix it.  Again, it's not a big issue as it is technically working, I just have to do the device manager steps everytime I boot into Windows.

Thanks for the help.

but your MB soundoption will be used and redirected to the hdmi. after you reenabled the sound you need to reinstall the gpu driver and withit the included audio thing that does the hdmi audio support. just uninstall all , both sound and gpu drivers. and install sound first and then the gpu driver. for me it works and i use my system on a TV with just a hdmi cable.  its a QN95B from samsung. and befor this same on a Sony TV and a Philips.

Just to make sure that everything is up to date please answer the following questions:

• Make sure that your Samsung Q90B firmware is up to date. For tht, you can contact Samsung.
• Were you able to uninstall and reinstall the current driver using Display Driver Uninstaller? 

If you have not completed the driver reinstallation check How to Use the Display Driver Uninstaller (DDU) to Uninstall an Intel® Graphics Driver for instructions and update the graphics driver to version 31.0.101.4314.

I have a similar issue, using an MSI Z690 based motherboard and an Intel A770 16G graphics card.

In my case, after booting, sometimes the monitor sound is available, sometimes it is not.

By not available, I mean it is not shown as an option on the Intel Arc Control Studio-Settings Audio Device menu.

I am using the latest Intel drivers, 31.0.101.2887, released 10/6/2023, less than 2 weeks ago.

My next step is to update the MSI BIOS for the motherboard.

Will let you know how that goes.

[psl]

Have not updated the BIOS yet.
It is a dual boot system; issues were noticed under Windows 10. Linux Ubuntu is OK so far.

I just installed my first a770 today. It is connected to a television with hdmi 2.1. Windows detects my tv properly as an audio device, and the hd display driver appears in my devices (twice, just like with the op, apparently). Anyway, no sound comes out of the tv. I tested with a different monitor with speakers, no difference. I uninstalled and reinstalled the ARC driver and disabled and enabled the audio devices and drivers in windows multiple times, and only once, for a brief moment did the sound come on, but it went away after I closed the arc control app and opened it again.

As a workaround, I can use the motherboards headphone jack and optical audio normally.

My system has a ryzen 5 3600 on an x570 motherboard with resizeable bar on.

Maybe this could be fixed in the future?

Thanks!!

I had ARC 770 sound issues on Windows 10 also. 

I just installed a new driver, 31.0.101.4953, which was released on Nov. 7, 2023 and so far all sound is good.

The sound comes through hdmi to an LG 4K TV, which I use as a monitor.

Looks like the driver update has fixed the sound problem.

[Lomppu]

Good to hear it works for you now!

Mine started a strange new behaviour yesterday: the sound works over hdmi for a random duration of time, usually 1-20 seconds, and always stops working for 5 seconds exactly before turning on for a random time again! So strange. But again, I just use the headphone jack and check every update if audio over hdmi starts working properly.

Hola, Tengo un tema con la Arc 770, la cual al momento de cualquier reproduccion de sonido tiene una leve pausa de 2 a 3 segundos y continua, una vez que ya esta en continua reproduccion no sucede. he probado de diferentes maneras sin obtener resultado con los controladores, incluso hice una instalacion limpia sin obtener resultados
 No obstante al retirar la grafica del MB el problema se soluciona
