No luck after version 6.0.9599. All later drivers still giving random disturbance from speakers on Gigabyte B450 Aorus M mobo.
Maybe you should check your LAN/Network, or (if you have) your Wireless driver. You should always use the "Not Support Power Saving" version of the drivers.
As i searched registry for 0002 key like yours, i got power settings options in all 0000, 0001, 0002. I changed those 3 settings in all these keys and restarted. Problems seems solved. I check for 2 days and return again to tell you. Later I checked again and found that Realtek system file and device description is matching in only 0001 key. But I changed power settings in all AMD high def device and also Fxsound device in registry . Hope there won't be any problem.
