Lenovo Yoga 13 fixes #7 – Windows 8.1 update causes a few issues

The Windows 8.1 update brings a lot of nice improvements, however it also creates two problems (well, let’s just say I only encountered two problems), both easily remedied. These issues are caused by something the Windows 8.1 installation does in refreshing the state of the device drivers.

1) Sound doesn’t work. Additionally, this causes videos / movies to fail to play with an obscure error. I want to start out by mentioning the first thing I tried to fix this, which seems to work but is in fact incomplete: If you go to the control panel (win key + x -> control panel), then open the Sound applet, it will immediately pop up a message saying that sound enhancements have been detected that are causing sound problems, and it asks if you want to disable these enhancements.  It is fine to click yes on this, but it only partially solves the problem. Sound will indeed work after doing this, but the Dolby Home Theater program no longer works. I suspect these are the sound enhancements that were referred to in the error message.

The correct fix is to download the Conexant audio driver from Lenovo and run the installation.  This simply reinstalls the same sound driver that was already there, but reinstalling it fixes it. Get the driver here: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS032590

2) The touch screen device was also reinitialized during the upgrade, so you will have to reapply the Fix #1 listed below in an earlier post in this blog. This is the fix for the touch screen going to sleep and missing the first swipe.

EDIT: A 3rd problem on my machine resulting from the 8.1 upgrade is documented in a newer post above – fixes #9.
