System Freeze and Audio Problem

I have just purchased a new computer but as i installed programs, a problem was introduced. I think I had seen the same problem on my previous computer, but that is a long story!

The effect is that the computer freezes for about 5 seconds and then continues. Associated with that is a message from the Realtek Audio informing me I have just plugged a device into the audio input. It does not require there to be any audio playing at the time this happens, though if there is audio, then that either goes silent or issues what can best be described as a buzz until the system resumes. The audio can also go into a state which i can only describe as like a stutter, where maybe it freezes for a few milliseconds at a time over a period of about 5 seconds. Sometimes this produces the Realtek message, though not always.

It seems that sometimes this can be triggered by activity, e.g calling a new web page in the browser. Often on returning to the machine after a period away, where the screen has blanked, waking the system up causes the Realtek message, but no obvious freezing of operation.

But the problem can also occur when the machine is not being used. I can be in the next room eating lunch and hear the audio freeze for the period associated with the problem.

With the new system, I started by sequentially installing the programs I required. This was a processed performed over several days as I was also working on the machine as well. Among the programs I had always installed was OpenOffice, I had been using this since it was first available, though I think generally LibreOffice now does better. But as I installed OpenOffice after several days without a problem, I heard the quality of the sound change and the problem started. On average, the problem manifests itself about once an hour, so i think the initial trouble free period up to the installation of OpenOffice identifies the culprit, but uninstalling it did not help. Windows repair tool claims to identify a problem and to have repaired it, requiring a reboot, but the problem still returns, so something somewhere is damaged. Google does nothing but confuse attempts to find the Realtek drivers which could be reinstalled.

I don't know where to go. I can't believe I am the only person suffering from this problem, yet I cannot find reference to such a problem on Google. So this is my last ditch effort to solve the problem before resorting to a clean install.
