I'm having trouble with my computer, specifically, the fact that as of last night, when playing audio and having an audio jack connected - my SYSTEM (NT Kernel & System) process, spikes up to use 45-55% of my CPU usage.
I have ran virus scan, malwarebytes and found small threats & removed them. Did not fix the problem.
I have updated my audio driver, and this DID fix the problem - or so I thought....(Temporarily)
Until this morning, where it started happening again.
If I don't have an auxilarly plugged into the audio jack and play sounds, this problem does not occur.
Simply having an audio jack in, and triggering the system volume max sound (by moving the volume in the volume mixer) will cause this spike. However any sound played from the computer (webpages, music etc,.) will cause the spike to occur. Making my computer run very slowly.
I initially thought I had malware, however this must be software/hardware related as I cannot get the spikes to happen any other way.
I'm completely stumped at this point, I've even tried a system restore to a point where this was definitely not happening, to no avail.
Any suggestions are greatly appreciated, if you need any more info just ask
