When these C state functions are enabled in the BIOS, the speakers make weird crackling noises whenever the CPU has to do something that sound like noises the old modems used to make. This is not only happening with onboard sound, but also with onboard deactivated and an external usb sound card. I tried many audio drivers, made no difference. Deactivating the C1E and the 3 state settings below that fixes it completely. BUT it also makes the system use twice the power usage jump from 27 watt to 45 watt in idle mode.
Now these distortions are only audible with very able amplifiers connected, with a crap audio end I could on hear them at maximum volume and with headphones they were not audible. SO I am wondering if this is a general problem but most people don't notice them.
My system:
Asrock Z68 pro3 (Firmware 1.40)
Intel 2500k
8GB Ram G.skill sniper 1.25
Seasonic X-400FL
Intel SSD 80GB G2
Windows 7 64bit
no graphics card,no HDD,no disc drives
Also the audio systems made no noises on the previous system and on my netbook.
Anyway to get clean audio without deactivating C-states?
