The audio output (from earphones) of my newly purchased PC is indistinct (i.e., only the singer's voice sounds filtered and distorted).

When I contacted the manufacturer, they suggested "total driver replacement (all installation)".

However,

"I'd like to avoid that"

These large-scale driver replacements have a fairly high probability of causing system crashes.

These problems have cost me a considerable amount of time in my life.

I would have to start all over again with PC setup, Office, IED (VSCode), Go language, MindManager, etc. I shudder just thinking about it.

I can't take this kind of risk for something as trivial as not being able to watch Youtube.

I have an extra USB port, so I will purchase this device to avoid the problem.

This form of thinking is called "conservatism".

Or, "opportunism".
