I was surprised that almost everything worked for normal usage apart from adjusting screen brightness and sound on my laptop.
I was wondering if anyone knows how to fix the sound issue.
I'm using Windows 7 by default and currently am using the Microsoft sound driver.
The original sound driver comes from VIA but after I reformatted Windows 7, I couldn't install it as the drviers were not digitally signed.
Thank you for reading till the end.
