Severe audio delay on ROG Strix Z790-E Gaming WiFi

[Tech127]

I've had this system up and running for 2-3 weeks.  I finally pulled a decent speaker out and plugged in into the 3.5LR jack.  It works, but there is a delay of almost a second.  This is on YouTube on Chrome, Brave, and Edge.  No difference anywhere. I tried VLC with a local high quality mkv file; same.

I wiped the m.2, did a clean install of Win 11 Pro, just let Windows install everything - no difference.

Tried everything snappy driver installer recommended....nope.

Made sure to disable all possible network connections, clean install again, this time after downloading the drivers recommended by MoKiChU and sticking them on the Win install USB.  This is an ISO put on USB by Rufus with all options checked.

Once Win was installed, I made sure to disable driver updates in Windows update.  I then installed all the drivers from MoKiChU, turned all windows updates off, connected the LAN, installed Brave from the USB; same.  VLC from the USB, local mkv, same.

I can't get rid of this stupid delay, even on bluetooth, or through the 3.5 on my monitor.

Anyone have any suggestions?  Do I need to just RMA this thing?

Have you installed your motherboard audio drivers? If that isn't helping, try MoKiChU's audio drivers at the link below and read his cleanup and install instructions carefully. The audio drivers can be a pain to get working correctly - not MoKiChU's fault, just the way it is 🙄

Pretty sure that you'll need the Realtek USB audio drivers (UAD - ASUS ROG SS3-DTS), but read through the threads to be certain. I suspect that your delay is probably drivers related.

Thanks for the reply.  I did a clean install, disconnected all LAN, installed ALL mobo drivers from MoKiChU including the (UAD - ASUS ROG SS3-DTS), but no luck.  Same problem

Here is the info he gave me.  I meticulously followed directions to the letter:

You need these firmware/drivers for your ASUS ROG Strix Z790-E Gaming WiFi motherboard (you don't need Intel GNA Drivers & Intel iGPU Drivers if you don't enabled them in your BIOS) :

[FIRMWARE] Intel ME (H610/B660/H670/Z690/B760/H770/Z790)

[DRIVERS] Intel Chipset/MEI/VMD (6xx/7xx)

- Intel Chipset Drivers

- Intel MEI Drivers (Drivers Only)

- Intel VMD Drivers (Drivers Only)

[DRIVERS] Intel Serial IO (3xx/4xx/5xx/6xx/7xx)

- Intel Serial IO Drivers (Drivers Only) :

Drivers - 6xx/7xx
[DRIVERS] Intel GNA (5xx/6xx/7xx)

[DRIVERS] Intel Thunderbolt

[DRIVERS] Intel Ethernet/WiFi/Bluetooth

- Intel Ethernet Drivers (Drivers Only) :

Drivers - I225/I226
- Intel WiFi Drivers (Drivers Only) :

Drivers - 9xxx/AXxxx
- Intel Bluetooth Drivers (Drivers Only) :

[DRIVERS] Realtek USB Audio (Intel 5xx/6xx/7xx & AMD 5xx/6xx/TRX40)

You have an ASUS ROG SS3|DTS Sound Unbound motherboard with ALC408x codec, so :

You need Realtek USB Audio Drivers (UAD - ASUS ROG SS3-DTS) from the first post of this thread.

Follow scrupulously your CLEANUP process then your INSTALL process, for the next drivers packages that I would release, you will can directly follow your UPDATE process.

[DRIVERS] Intel Arc GPU (Axxx) & iGPU (11xxx/12xxx/13xxx CPU)

Hi,

If your sound latency issue also occurs with Bluetooth (which does not use your Realtek audio controller), it is not related to your Realtek audio controller drivers.

Follow these 2 TIPS (also visible at the bottom of the first post of all my audio drivers threads) :

1) Disable hibernation :

- Right-click Windows Start button then click Search.
- Search for cmd. In the search results list, right-click Command Prompt and then click Run as administrator.
- If/When you are prompted by User Account Control, click Continue.
- At the command prompt, type powercfg.exe /hibernate off and then press Enter then close the Command Prompt.

2) Enable MSI (Message Signaled-based Interrupts) mode on all your supported devices (see the column "supported modes") with MSI Mode Utility (Right click on "MSI_Mode_Utility_v3.exe" > Run as administrator), then Apply, then close MSI Mode Utility & restart your PC.

If your sound latency issue persists, please contact ASUS Support and/or open a thread in this ROG Care category : https://rog-forum.asus.com/t5/gaming-motherboards/bd-p/HSS_MB.

Thank you very much for the reply and guidance.  I followed the above tips exactly and It helped substantially.  It still isn't perfect, but at least now it's very close.  Roughly 0.0625~0.125 of a second behind the video.  At least it doesn't look like an old kung fu movie anymore.
