5 Second Audio Delay When Sound Has Not Played for a Few Seconds

[evieamity]

I should note that this issue was present right out of the box when I purchased my laptop. Also, this issue was present on my old HP laptop which was a 2017 model, (I apologize I don't have the model number for that one), so I am beginning to think this is a continuing problem with many HP laptops, and not some defect.

This issue only happens with devices like headphones plugged into my laptop's AUX port. Whenever sound has not been playing for more than about 3-5 seconds, if I attempt to play something such as a video or some kind of audio, I will get no sound for approximately 5 seconds, then the sound finally pops back in.

This is rather annoying, as it results in me needing to start and immediately stop a video, wait for a few seconds for the audio to kick in, then play so I don't miss any part of the video. Over time this has become infuriating as I've searched endlessly online and still cannot find a solution that works for me.

I found this forum topic here and after making the appropriate registry changes, I find that after rebooting, my issue persists. This is because every time the computer is rebooted, the registry changes revert back to their original values. In my case, the CoversationIdleTime reverts back to "05 00 00 00" and PreformanceIdleTime reverts back to "05 00 00 00" as well (this value is slightly different than in the case in that article where it was "0a 00 00 00"  by default, however I do not believe that being different is the cause of this issue).

Operating System: "Windows 10 Version 1903 (OS Build 18362.239)"

Audio Driver: "Realtek High Definition Audio(SST)"  (I think version 6.0.1.8393, as when I checked the driver version, it said the file C:\WINDOWS\system32\drivers\RTKVHD64.sys was on that version.

I appreciate any help you all are able to offer. Please let me know if you need any more information from me that would be helpful, thank you.

Edit: I found this video here. To anyone like me who still has not found a fix, they can open this video, set the quality to 144p, and leave it running in the background. As a temporary fix, this will make your device "believe it's still playing audio" so that it won't make the AUX port audio sleep. You could also download the video as an MP3 using some video downloading tool and open it in the background to accomplish the same thing.

I don't know your old machine therefore I can't answer.

Regards.

Reinstalling that was among the first things I've tried, however it unfortunately resulted in no difference. Also, I only mentioned the other machine for the purpose of explaining that this is not simply a defect. I do not need assistance with the old machine, only the new one, which is an "HP ENVY x360 - 15m-cn0011dx", as described in my initial post. Regardless, I appreciate the information.
