G51Jx 3D audiodg.exe (high cpu usage)

I bough this laptop and I'm having a problem with audiodg.exe: sometimes, when I have foobar2000/wmp playing a song or when I'm playing a game, audiodg.exe raises its cpu usage to 13% (100% on one core). I've already tried to check the option to disable all audio enhancements, to update the realtek audio driver, to uninstall the creative software and to do a clean install of windows 7, but nothing worked.
Any suggestions?
Btw, the audio codec on my laptop is ALC663.

 

Hi joaomaradao, and welcome to the forums

I'd first try disabling the audio enhancements in your audio settings and see if that helps.

 

Hi, thanks! I've already tried that (for all the output and input audio devices), but it didn't help :confused2:

 

Sorry about the double-post, but after using my laptop a bit more I found another problem: random connection lag.
I was playing S4 league and suddenly I noticed that my ping to everyone else was within the range of 200-400ms. Then I checked speedtest and got something between 0.25Mb/s and 2.5Mb/s (comparing to the 8.7Mb/s that I usually get).
After updating the AR9285 driver (to 9.0.0.173) I never got that low bandwidths (5.xxMb/s was the lowest), but I'm still having some random lags.
You can check those pingtests:
(While lagging)
(Not lagging)
The most weird is that the WiFi signal is between 40% and 60%, and I don't notice any significant signal drop during those lag times.

Still about the audio problem: do all G51Jx models come with ALC663?
I'm starting to think that I was only lucky on the RAM (it's 1333MHz instead of 1066MHz ).
