Arc A750 short silence issue while seeking Youtube videos with DisplayPort

[Leav]

My monitor is connected to 1st DisplayPort output of A750. When I was watching Youtube video (using Firefox 116.0.3 64bit) and seeking, I noticed that there was a short audio silence (1~3 secs) after the video starts to play.  For example:

https://www.youtube.com/watch?v=leIK1aUOF-Q

I can reproduce this issue by pressing "5" key to jump to 50% of video.  Every time I pressed "5", I can see the video jumps, starts to play, but no music for about 3 secs.

I also tried:

- Connect my monitor via HDMI

- Watch Youtube video using Chrome via DisplayPort

Interestingly there is no such issue.  The music just goes well.

Here is my configuration:

- OS: Windows 10 22H2 19045.3324

- CPU: AMD R5-3600

- MB: Gigabyte A520M

- Video: Intel Arc A750, driver 31.0.101.4644, PAR enabled

- Monitor: Philips 288E2, 4K@60

• When did the issue start?

Both my A750 & monitor are newly bought

• Is the audio coming from the monitor or any other audio device (headphones or speakers)?

Monitor's built-in speaker

This issue also occurred if I plug a headphone into Audio-Out behind the monitor

• Are you able to test using a different audio device?

Audio-Out behind motherboard -> Headphone => No such issue

• Is the issue only present on YouTube? Does it also occur on other video websites (Twitch, Netflix)

Netflix + Firefox => Bad

Netflix + Chrome => Bad

Also occurred when dragging Win10 system volume control.  Sometimes I heard the chime sound and sometimes not.

Hello Leav,

Thanks for the information provided.

Based on your system report, we noticed that your graphics driver is 31.0.101.4644. There is a new driver version, 31.0.101.4669, and we recommend you install the new driver version. To discard the possibility that the issue is being caused by a previous driver file, try running the Display Driver Uninstaller. Check How to Use the Display Driver Uninstaller (DDU) to Uninstall an Intel® Graphics Driver for instructions. The DDU tool will eliminate all drivers and leftover files from previous driver versions.

Best regards,

Hi Jean,

Updated to 31.0.101.4669.  The issue still exists.

BTW I read the release notes and no DisplayPort audio updates are mentioned.

Hi Jean,

So it seems like an OS issue.

I tested the new driver on Win10 22H2.  This audio issue still exists.  Unfortunately I have no plan to upgrade to Win11, so I can't confirm if this issue was fixed.  Hope Intel can push MS to patch Win10 also.
