dell precision m6800. win 10

it just happened a couple of days ago, the drivers are up to date and cant see any errors in the device manager.

there are are no windows updates to install

it happens playing video etc but also system notification noises are distorted too.

the whole laptop has kind of gone sluggish too, cursor lags and it takes longer to do anything

virus scan is clean, does a clean up, defrag and chkdsk, with glary utilities, and 360 internet security

any ideas what this could be?

thanks
