Welcome to the forum.

I'm going to suggest you look in a different direction. Your problem could be software-based. Dell and other vendors load lots of bundled software that may be running in the background, and interrupting your digital audio every so often. How many programs are running in the background? How many are showing on your taskbar?

Try running the free DPC Latency Checker. For Windows 10, 1000 is the correct minimum reading (not zero). See if you have red spikes. The website gives instructions of what to try if you do.

Windows Process Monitor gives even more details about the same condition, but you're on your own.

Is this a laptop? The first thing to do with any Windows laptop is go into the Power Settings and bring the CPU up to 100%.

Also while in Power Settings, make sure the USB ports are not set to shut down after a few minutes.

Write back with your results, or questions.

ps And whatever you do, don't use the headphone jack into an amplifier. Not only is it a level mismatch, but those little jacks break easily and, more often, can give a tremendous noise into your PA when jostled.

EDIT: This easy article just posted by Dan, another user here, tells about the power setting adjustments for digital audio on a Windows computer.
