Annoying issues on new Win 10 build

I built a Win10 machine several months ago and I finally have time to chase down a couple annoyances. The first being noises that emanate when playing music files from any one of three players that I have. When using VLC I get a noise at exactly 1:05 into every music file. Probably .25 sec long. Also, when playing youtube videos I get the same exact sound at intervals I have yet to determine but they are pretty regular and spaced probably 5-10 minutes apart. The sound is like a digital stutter for half a sec. I also have some noise that sounds like snaps and pops on vinyl being played on a turntable.

The next problem is weird mouse lag or just really slow to move with what I am doing for brief periods.

This PC is not lacking anywhere except maybe the sound card which is kind of obvious. I am using the built-in sound device but on this machine, I can not see why it would be a problem. For both issues, I have uninstalled and reinstalled, updated whatever drivers. I have not been able to improve on these issues at all.

Do you have your mobo drivers installed to include the latest BIOS? What is make/model of your external speakers? How do they connect to the PC? Is the connection fully seated?

The connection is good it is a 3mm plugin the back, had the speaks (Klipsch 2.1) for years and I tested them on other devices, never an issue. I did update the bios very early in the build. The entire time with this machine and getting sound from it has been an ordeal.

Not the issue. I recorded the sound with Audacity and the noise did not appear on in the waveform. It was just blank on the recording. Trust me though, there is a noise on every audio file at 1:06.

You've ruled out software as the issue as it happens with the 3 that you use. So that leaves hardware. It's either the speakers themselves, mobo or sound chip on the mobo or the audio driver. From time to time, parts on a new mobo can and do go bad. Is the mobo still under warranty?

Kind of what I am thinking too. Mobo issue but hopefully isolated to just the sound chip. I have been building my own PCs for almost 20 years and sound is always a problem early on and then I get it worked out. Most of the time by buying a sound card, which is probably what I am going to do. I bought the board in Oct 17, not sure about warranty but I would rather not tear it down and rebuild if I can install a 3rd party sound card.

You might ask the vendor you got the board from if they will cross-ship a new one, usually give a week or two to send back the original. In my experience assembling machines in computer shops since '94 it takes longer to install software than to install or replace parts.

Could it be related to a microphone in some way?
