Well maybe the issue is really with the drivers... Installed IRST drivers only on my PC and the issue is back (Mini-freeze then audio jack notification). From what I experienced it looks its something related with ODD's after some time in low power mode on the HDD's because whenever it happens I can hear like when the HDD start to spin up and also the ODD on my PC do the same thing even when there's no disk on them. @toyo do you have any ODD on your PC? asking because you don't have this problem, but have a pc very similar to mine.
