ASUS Laptop Sound Drivers

Hey guys,

I've been helping my friend troubleshoot over a combination of phone/Teamviewer and cannot for the life of me figure out what next I should do. She's using an ASUS K55N-DS81 laptop, new from Amazon. It's running Windows 8 64-bit with 4GB of RAM.

Main problem: her audio doesn't work, and hasn't worked since she got it about last week. When I go on over to the Sound Panel, nothing is present except for a single unplugged "High Definition Audio" to an HDMI output in the Playback tab; the rest are empty. So, this must be a driver problem.

Upon opening Device Manager, there are over ten devices with the name "Unknown device on high definition audio bus", none of them with any form of relevant info in their properties. I think to myself, this is simple; I go to ASUS, download the drivers, install, restart, and BOOM! Sound, right? Wrong.

I've tried running Setup from the ASUS zip; I've tried running Setup from the Realtek zip; I even found a really obscure fix on some search a while back with a link to 4shared asking me to disable digitally signed drivers and install the included .ifs, but nothing. And thus, I ask you guys for pointers.

Windows Update shows nothing for Audio Updates.

I haven't tried uninstalling what drivers I can and then simply restarting; probably gonna go with that next. Thanks everyone

Have you tried plugging headphones in the audio jack? It is possible that the physical speakers themselves or the card maybe faulty rather than a driver issue.

Many Thanks,
Josh

With the amount of problems, first thought is to do a complete reinstall using the ASUS restore procedure (assuming ASUS has this on the PC). Otherwise I would return the PC for either another or a different model. There is no reason to "fight" problems such as this with a new PC.

I used to do work on another PC vendor's forum and occasionally (not very often but it would happen) one would come out with a bad "load". Reloading from the vendor's restore partition on the hard drive usually solved the problems.

Do not install unsigned drivers, especially if you're on x64.

Re-install the official audio driver and reboot.

ASUS drivers here:
ASUSTeK Computer Inc. -Support- Drivers and Download K55N

(select OS: Win8 64 and go to audio section)

If after reboot it's still not working, try to extract the zip and install it manually through Device Manager (Control Panel -> System).
