same problem here. Let's keep the thread updated.
First time I buy a premium laptop and I got this annoying issue…can't believe it!
3.5 months I come to this thread to see if somebody figure out a solution as I lost faith in Dell after being a customer for... 3.5 months.
The easiest way I resolve the issue every 60 minutes is: Right click on Sound icon / Spatial sound / Toggle between Off and Windows Sonic for headphones.
For audio problems you can test different drivers/programs configurations with DPC Latency Checker. Another good tool is LatencyMon, which tells you which driver is causing latency problems with a detailed report. However it is not always easy to find out the real cause, even with this tool.
In my case I kept for few days DPC latency Checker open during my regular sessions, and I discovered that using tools that check the Dell temp sensors (like Aida or hwinfo) dramatically enhanced the latency of the system (4000+ microsecs), leading to audio popping. So I figured out what was causing my problem: too much attention to the details of my machine!
With this tool you can also notice that in certain conditions the latency is reasonably low (below 1000 microsecs), while the more common situation is with a latency slightly higher (roughly 1300 microsecs) and this difference could be explained by Dell engineers here. However, audio problems start above 2000.
**bleep** to see such an issue on an high end laptop, my 5 years old mid level Asus beats the **bleep** of my brand new XPS 9570 when it comes to audio production... Really disappointed 😞
