Ok, thanks for responding to that inquiry. It doesn't matter whether it's listed as a bug-fix or not. Professional Technicians know that this is the process to follow; you do not. No offense. Here's a link on how to flash your BIOS; general ASUS laptop, not for your specific model:
how to flash your bios on an asus laptop? - Bing video After you've completed the BIOS flash, like the video above reboot your computer, and go into the BIOS using
<F2> key or similar for your model (consult your Owners Manual for exact key to use; every BIOS is different). Make sure you updated to
v209; it should show that on the home or landing page of the BIOS screen. If it's the new correct version
(v209), you did it right and you're good to go!
Reboot your laptop and retest your sound. Check to see if your Realtek installed driver in Device Manager looks right; it should have more devices as per my earlier post. If it does, the outdated BIOS was the problem.
If the problem persists, and the sound driver isn't displaying the right devices there's a good chance your Mobo is faulty and the unit needs to be returned the place your purchased it at for factory repair/depot repair/exchange/refund. You haven't yet mentioned whether you purchased this laptop from a retail store or from an online reseller etc. That might tell us more.
If the BIOS flash fails, and you are stuck at the old v206 version, then you either did it wrong or the Mobo is faulty, which has the same end result: you'll have to take the laptop back to wherever you bought it and get them to fix/replace/refund it. Period. As a sidebar, when you do the BIOS flash incorrectly, you may never be able to boot your laptop again as it can be easily bricked!
That's why I recommended if you've never done it before to carefully consider the consequences!
It is very risky for sure. Another thing you might consider is calling up ASUS and talking to their tech support. Some manufacturer's consider BIOS flashing during the 1st year of warranty coverage a warranty violation, and they will not repair it for free.
If you then brick your Mobo attempting to do so, they won't repair it nor replace the Mobo with a new one!
Personally, and I'll say it again,
I'd recommend you get this done professionally, find out from ASUS or the Tech (if you take it to one) whether a bricked Mobo from a failed BIOS flash is covered under the warranty for your model laptop or not. If you were bringing it to me to fix, that's how I would do it.
If they don't cover it, and most laptop makers these days do not cover it, you have a
$275-$1500 repair on your hands to fix it.
This discussion is for you, and not everyone. The fact that you are asking us how to Flash a BIOS tells us you've probably not ever done it before, and thus all the cautioning. I've had customers try this and fail, and they get very very very upset when they brick their $1,0000 new, less than 1 year old laptop!!
Let us know how it goes.
