Audio Lag over HDMI

[PoBear]

Hi

I am using my monitor to playback sound, the monitor is connected by an HDMI cable to the Nvidia GTX 1650 video card. The Driver is reported as the NVIDIA High Definition Audio Driver 1.3.38.34 dated 8/6/20 

When playing sound from silent there is a delay/lag before the audio is heard, this applies to system sounds as well as video music playback when the sound does start it is in sync with the source so this is the first few seconds being lost rather than not being played.

The lag is between one and three seconds although on occasions it can be longer.

If the audio is stopped and then restarted then it will play without the lag providing playback starts within about 5-10 seconds of it stopping, outside of this then the lag comes back in.

I've done all of the diagnostics I can find and nothing is showing, I've also changed the cable with no effect.

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Have you tried with different internet browsers?
• Have you tried playing video from your storage drive?

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

1. In Windows, type find and fix audio into Search, or right-click the speaker icon  in the taskbar and select Troubleshoot sound problems.
2. Select Find and fix audio playback problems or Find and fix audio recording problems from the Search results.
3. Click Next.
4. Select the device you want to troubleshoot and click Next.
5. Wait while the troubleshooter detects problems and makes changes (or prompts you to make changes).

If the issue persists then I suggest you to perform a BIOS update on the laptop via this link. Please ensure that the charger is plugged into the laptop until the BIOS is updated successfully.

Finally, please initiate a test on the audio. The following steps will help:

• Hold the power button for at least five seconds to turn off the computer.

• Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

• On the main menu, click Component Tests.

• The Component Tests menu displays. Your Component Tests menu might be different, depending on the components installed on your computer. 

• Please initiate an Audio Test - The Audio Playback Test checks your system to make sure the audio device is functioning properly. During the test, a few music notes are played in sequence and then repeated. This test takes 1 minute to complete. To run the test, click Audio, and then click Run once. Choose either the speakers or the headphones. When asked, enter the number of notes you heard.

Hope this helps! Keep me posted for further assistance.

It looks like HP Software Component 1.24.2054.0 or 4.2.232.0 may have fixed the problems as when I went to provide you with more information I realised that the problem had gone away, these were the only changes to my system since I originally reported the problem.

Thanks for your help.
